hello, later looking error fatal error:

call undefined method stdclass::ondisplay()/home/content/r/m/o/zammito1234/html/mywebsite.com/libraries/joomla/html/editor.php on line 268

i tried 2 things
first replace in order folder involve issue , nothing fix
then try site joomla 1.5.15 nothing fix
i think not problem of secuence in joomla 1.5.12 1.5.15 nor jce plugin because before working fine.
i read post in russian forum sugest remove lines in editor 268 fix problem me in "jce", "tiny" , "no editor"

try this

in orginal

// try authenticate -- add array if authentication successful
$resulttest = $plugin->ondisplay($editor);
if ($resulttest) $result[] = $resulttest;

remove 2 lines have

// try authenticate -- add array if authentication successful

i hope succesfull
