[TYPO3-english] Serious problem after upgrading to 4.3.3

[J. Bakshi]

Dear list,

I have found a serious problem after upgrading my typo3 from 4.2.10 to
4.3.3 The extensions /rgsmoothgallery/ 1.5.1 and /media_center/ 1.0.2
are not working :-( I have double checked that the youtube links are
still valid but media_center can't play those links any more . And
rgsmoothgallery is also not able to display any pictures where the
folder settings are all correct and pictures are still there. the most
important thing those are working well before up-gradation. Does any one
face the same ? I have even re-install rgsmoothgallery and media_center
to create the databases properly if there is any problem during database
compare but no luck :-( any solution/suggestion/help please ?

eagerly waiting for a response.
