I have a site migrated to 2.5 using jupgrader and it worked beautifully. Upgraded to 2.5.1 and then 2.5.2 now I find that I can save articles from the backend (haven't tried the frontend). The save/cancel/etc. buttons are not working.
I investigated this and it turned out that there as a JavaScript-error in validate.js (line
:
Code:
Uncaught TypeError: cannot call 'getElements' of null
This seem to have something to do with adminforms validation.
I downloaded and installed a completely fresh 2.5.2 which worked.
I overwrote the whole installation with a fresh 2.5.2 which did not fix the problem.
How can this even be a problem if it is the identical same code in both installations? There are a few extensions I use (akeeba, fwgallery, gcalendar, jce and a jat3-template), but I don't think any of them is causing this, right?
What to try next?
Also, there is no Joomla version shown in the footer, how come? Does this indicate some malformed HTML?
