[TYPO3-dev] Export of extension not possible (?)

[Alexander Födisch]

Hi,

when I want to download an extension developed by myself (save as t3x), I got the error message:
"#1270853981: TYPO3 Fatal Error: An unexpected error has occurred. There are problems with your extension key 
or with the extension data."

What's wrong there? What is checked by Typo3 backup routine? Any ideas?

I also created on another Typo3 system an extension with same name and copy all my files to this extensions 
directory -> same error. So something is wrong with my extension (which is working). But what??


Thanks,
Alex
