No error if missing loaded extension
I have some global extensions used in different sites.
Step to reproduce the error.
1. Load an extension, by instance Realurl
2. Delete the extension from /typo3/ext
3. Back to EM in BE
4. no error message.
Shouldn't this be reported by TYPO3?
I found this cause I was upgrading my test installation of TYPO3 4.3 from beta2 to beta3 and by mistake I copied the beta2 /typo3/ext inside beta3 /typo3/ext instead of /typo3
So I ended with all my global extension inside typo3/ext/ext.
Nothing helped me to find my mistake until I found that in the FE of my test installation it was missing the Google Analytics code cause the rsgoogleanalytics was not loaded. Same for Realurl and other extensions.
I did tested it and it happens also with TYPO3 4.2.
