TYPO3 Core

You get an error 404 when calling a file, which in fact is there and can be loaded? That's strange...

Can you have a look at the server logs? They should tell you, which file could not be opened and why.

Have you tried deleting and redownloading your copy of the source code? Maybe one of the loaded files got corrupted?

Hey Christopher
I'm sorry for the confusion caused, I'm not getting a 404 error or a (page coud not be found) error what I get is just a blank page after clicking the edit buttons, this happens in the page view and in the listview.

Following file is loaded in the pageview pressing th edit button:
http://www.myurl.ch/NEW/typo3/sysext/cms/layout/db_layout.php?id=578#"

And this is the page which should be loaded in the listview:
http://www.myurl.ch//NEW/typo3/db_list.php?&id=578#

I replaced both to check if they are corrupted but that changed nothing...

I met a other guy in typo3forum.net facing exactly the same problem but also without solution yet...

Very best regards and many thanks for looking into that.

OK, I just realized that you did a bigger update (from 4.1):

The code in the TYPO3 page module, which makes up the Edit button uses JavaScript.
Do you use an extension, which modifies the output there? E.g. how the content element buttons are displayed? Maybe an incompatible skin extension? Do you get a JavaScript error (on the console in Firefox)?

Or maybe you get a PHP error which causes the empty page? Enable the display of PHP errors and check, if something is displayed, when you click the Edit button then.

Hi Christopher

the only skin extension I have installed is "t3skin 4.4.0"

Using the console in Firefox shows a lot of warnings starting the backend, all are related to some files in the ...compressor... path no warnings or errors are shown pressing the edit button...

Regarding the PHP error, could you please tell me what I exactly have to do to enable it an where the errors will be shown...

Check carefully your .htaccess file.
The BE-compression has changed a lot and there are some modifcations needed.

To test, whether this is the case, disable BE compression in localconf.php

Hi Björn

As I do not have .htaccess files in that installation... Please tell me if it is needed and what should be the content.

Could you please tell me how to disable the compression in the localconf.php? ...I'm not a pro... :-)

Warnings are OK I think. So no JS errors.

You can activate the display of PHP errors in the Install Tool. Search for an option called something like displayErrors and set it as described. If there are errors, they should be shown in the frame which reloads after you clicked the Edit button.

You find the needed code for .htaccess in the Update Wizard for the compression level.
To disable compression, you must set TYPO3_CONF_VARS[BE][compressionLevel] = 0, which you also can do in the Install Tool. When this option is not set to 0, the described rewriteRules in .htaccess are needed.

Christopher Many Thanks for your Help the Problem is solved!

After displaying the php errors i got following Error Message:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2 bytes) in /home/baselsno/public_html/NEW/typo3_src-4.4.4/typo3/contrib/jsmin/jsmin.php on line 146

So I setted the Memory limit from 32MB to 64 MB and everything is working now...!

I'd realy like to thank you for your efforts and explanations and wish you and your family a very nice christmas!

Thanks again!
