I believe that the ‘jQuery’ is undefined bug with IE is still occurring in EE 2.3.1 - Build: 20111017.
When trying o publish an entry which includes Wyvern v1.3.2 IE 7 and IE 9 throws the following errors:
As per another report In IE8 Standards Mode everything works fine. Adding <meta http-equiv=“X-UA-Compatible” content=“IE=8”> in system\expressionengine\views\_shared\header.php to force IE9 to render in IE8 Standards Mode is a quick and dirty fix to avoid the errors.
Anyone using NSM Morphine Theme you still will get the following errors in IE 7:
SCRIPT1028: Expected identifier, string or number compressed.js, line 11 character 628
Removing commas from the code before the } fixes this issue:
$(opts.triggerSelector,$self),} and inputDeleteKey:"delete",}
Is there an appropriate solution to this issue without the need to hack the core files?
This question may be related to a resolved thread. Which to be doesn’t look like it is resolved.
