Error: 500
JHtmlBehavior :: mootools not found.
How can I avoid it ? joomla use the latest version. Thank you

More detail please!
Which registration module is in use?
"mootools" not found is based on Joomla 2.5

Hi, i used joomla 3.4 and module base of registration. The site www.solutionslab.it/twt .

Hi there,
1.) Did you upgrade your site from Joomla 2.5 to J3.x?
2.9 Did you uninstalled the old theme and installed the new theme on Joomla 3.x

Anyway this could help you:

Because motools problem is only available if you are using an extension or theme for Joomla 3 which is based on Joomla 2.5 code

Hi,
i used a quick start of your package...

OK, we have found the error and this bug will be fixed in the next version.

How to fix it:
Delete the compete folder "com_users" from > jp-xtra/html/com_users/*
