TYPO3 Core

Can you please have a look at your PHP error log or enable the output of error messages using the displayErrors property in the Install Tool?
Think there occurs a PHP error.

no, there are no errors in the error_log !?

Hi Guys, there is exactly the same behaviour in a view of my typo3 sites.
in several Versions available: 4.4, 4.2 and 4.1

Also no error in the Error Log.
I've remarked a seccond problem which might help to find out more:
As well on all Web-Sites there is ameos drag and drop upload installed. Instead of the Upload-Mask it only shows a red cross. I've tested it in Internet Explorer 7, Firefox and Chrome. All these Application seem to get some Troubles with the extensions. Either with the integratet Upload, as well as with the drag and Drop Plugin.

Further information i've found in the java console while debugging the app:

Java Plug-in 1.5.0_10
Verwendung der JRE-Version 1.5.0_10 Java HotSpot(TM) Client VM

Any suggestion how to prevent this crashes/causes?

Workaround: Somehow there seems to be a problem with your flash-Plugin or any cache file on your server- or local system.

Well, instead of using the direct upload, i'd advice you to do following:

1) Login on your TYPO3 BE
2) Go to User Tools on the Left > User Settings
3) Then click on Tab "Edit & Advanced functions"
4) Uncheck "Enable Flash Uploader (requires Flash 9+)"
5) Clear Cache and retry upload with the good old static upload-function

Does this work in your case?

Workaround In Deutsch
1) An TYPO3 Admin-Maske anmelden
2) Links auf Benutzerwerkzeuge > Einstellungen klicken
3) Dann die Registerkarte "Bearbeiten und erweiterte Funktionen" wählen
4) Dort das Kästchen "Flash-Schnittstelle zum Hochladen aktivieren (erfordert Flash 9+)" deaktivieren (- also: Haken raus)
5) oben rechts im TYPO3 auf Blitz-Symbol und "Alle Caches löschen"

nun sollte es funktionieren.

I hope these user-settings did help.
Important: If you have more than one backend user, do this step in all the accounts.

Cheers

Michael, are you also using AmeosDragNDropUpload? Then it's not a core issue...

Hi Steffen, the main-cause is in the in TYPO3 integrated File-Uplaoder. Both of us have installed a newer Version of Flashplugin than 9+.

The Ameous is just something which i've tried to ship around the problem and recognized there turns up another problem.

Something must be wrong with the Flash-Upload which was integrated in the t3core.

No, there is no AmeosDragNDropUpload installed

Have you tried setting displayErrors = 1 in the Install Tool?

Michael:

Is there remaining a really white empty site after uploading a file? or does it realod the page in the thierd, right frame? in my case the page reloads and shows still zero files. Even manually reloading the frame via refresh-button helps.

Steffen:

Yes, I did. maybe I didn't look up on the right place... well i looked through all the logfiles which accessible via TYPO3 BE. Nothing strange turned up in there...

actually there is one entry, but this wouldn't fit in this thread. Somehow moving documents doesn't show any information about the moved docs, instead TYPO3 writes a parameter called %s which doesn't mean alot to me:

This is the mentioned entry in one of the log files...
File "%s" moved to "%s" (msg#2.3.1)

Well I've also tried a few more things:

- f.e. to uncheck the thumb-preview in fileliste, and the other two options and this didn't help.
- another thing I've tried: to clear the temp-files and clear cache after updating the the config via install tool
- i've also updated the java and flash-plugin, but didn't help either...
- and last but not least..: I've also tried to upload into any directory with several different file-permissions. 0777, 0755 and so on...

maybe some silly tries of me, but sometimes such easy tries helped me to solve a problem ;)

One thing worked, if I switch of the flashthing (see above) via workaround, the old upload mask turns up and upload works well. but still, that seems not to be the solution.

Thank you for help guys.

In one of the TYPO3 Installations (Version 4.4) I found following message:

All of your uploads failed.

If this problem persists, please try another browser, contact your administrator or disable this "Flash Uploader" in your User Settings.

Detailed problem description:
403

Is it possibile, there is one not showing up the message prompt?

I don't know, why no info is shown. I aimed to improve the error messages.

status 403 has been sent by the web server. I wonder, why you have no access to the upload script. Could you have a look at your access_log, what the request was and try to access it in your browser?

when i acccess the script (/typo3/contrib/swfupload/swfupload.swf) in the browser, there is no error message (only undefiened from flash)

even in the error_log there is no entry

No, the flash uploader sends the files to ajax.php. Please search for a request to this file (typo3/ajax.php), there should be a request with code 403 (at least in the second installation).

Well, maybe this helps: It's not the 403 - instead the 406 Code. mod_security

1) Log-Entry - 406 Code
[Tue Aug 17 21:02:05 2010] [error] [client 62.203.133.114] mod_security: Access denied with code 406. Error processing request body: Multipart: final boundary missing [severity "EMERGENCY"] [hostname "customer-domain.ch"] [uri "/typo3/ajax.php"]

2) Log-Entry - Some of the path seem to be corrupt
(That's the message when I call script(/typo3/contrib/swfupload/swfupload.swf directly
[Wed Aug 18 14:04:04 2010] [error] [client 80.238.229.15] File does not exist: /home/httpd/vhosts/customer-domain.ch/httpdocs/typo3/contrib/swfupload/undefined, referer: http://www.customer-domain.ch//typo3/contrib/swfupload/swfupload.swf

3) Log-Entry - with RSA-Message
[Tue Aug 17 20:17:43 2010] [warn] RSA server certificate wildcard CommonName (CN) `*.metanet.ch' does NOT match server name!?

Possibile this is caused by mod_security in httpd.conf? does this parameter have to be on or off for having the application working?
Somehow strange, the provider must have changed the value - because ameos worked fine bevor and from one to the other day - this feature and also the flash-uploader strucked....

And it seems to be the same cause as in the Ameos Drag & Drop Upload, which i won't need after this works fine here...

4) Log-Entry - Ameos MSG also 406 Code

[Tue Aug 17 20:18:11 2010] [error] [client 62.203.133.114] mod_security: Access denied with code 406. Pattern match "(libwww|lwp|Twiceler|Indy|Yandex|Java)" at HEADER [severity "EMERGENCY"] [hostname "customer-domain.ch"] [uri "/typo3/AmeosDragNDropUpload.class"]

Manuel,

okay.. thanks for the information. Looks like, there are way more error reasons, which could be added to the error message ;-)

1) what does the flash uploader show? Does it show you "406" as problem description
2) Think it's just when a parameter is missing, so I wouldn't care about it
3) SSL is a big problem for flash: It can't handle self-signed certificates and fails without any reason. AFAIK the error message about the wrong CN is only outputted while server startup, isn't it? But at least that again leads discussion into the direction of SSL.
Do you use SSL to access the backend? What happens when you use plain HTTP? Certificate self-signed?

I've searched a bit for the suhosin problem and e.g. found this:
http://forum.joomla.org/viewtopic.php?f=428&t=267886

Manuel: You are not experiencing the "empty frame" problem, right?

<b>Please open a new bug report, if you (not only Manuel) have a problem with the flash uploader, but not an empty frame. It's heavy to have simultaneous problem threads at one time.</b>

I would even suggest to open a topic in typo3-english list. Could (maybe also Michael, too) you please do this? And please try to summarize your setup, what doesn't work (and what's the error) and what you've tried yet.

Thanks
Steffen

Thanks Steffen.
I did so.... hope that's all right:

TYPO3 english list? where is that at?

Thanks.. will have a look later.
