Fatal error: Call to undefined method - Joomla! Forum - community, help and support

-

this site has been such headache me. had problems previous template bought new one. after hassle installation got working. however, after getting end of site discovered whenever select category or item edit in k2 following error:

fatal error: call undefined method stdclass::ondisplay() in /home/content/62/9006362/html/century21/libraries/joomla/html/editor.php on line 459

can please suggest how remedy this? clues have found have said compatibility issue happens when trying load older template onto newer version platform. have double , triple checked. 2.5 template on 2.5 platform.

was able fix 1 myself. else runs problem, error refers plugin not working properly. easiest way found fix go through plug ins 1 one , disable them until find 1 isn't working. once disabled error should go away.

[mod note: glad managed resolve yourself. thank providing solution issue others see.
marked resolved]
