TYPO3 Core

Here is the same tt_products dev. version exported from TYPO3 3.81. which works fine for reimport:

http://story-castle.net/fholzinger/development/T3X_tt_products-2_4_6-z-200602271442.t3x

I got this error everytime I marked "get latest translation" or "download documentation" when either of these were not available

Axel, this is indeed often the cause of such errors. But I think here the T3X file is uploaded directly, the TER is not involved. Right?

Yes, I have exported the T3X file with the Backup function in EM. I did not use the TER for this.

I just tried installing a CVS-TYPO3-exported nothing extension and one directly from TER2 on 3.8.0 and it worked.

When installing the extension attached to this bug report, it fails, but the real error message (that doesn't get shown due to a bug on old EM versions) is

"Error: MD5 mismatch. Maybe the extension file was downloaded and saved as a text file by the browser and thereby corrupted!? (Always select "All" filetype when saving extensions)"

I then imported 2.4.6 into a CVS-TYPO3, exported it again and could import that file into 3.8.0 without problems.

So it seems that your file got corrupted for whatever reason.

Please check again carefully(!) and reopen if this really is an issue.
