Look for multiple instances of jQuery
Right click on your page and select "view source." With the source opened, use the search feature of your browser (often CTRL + F) to search for ‘jQuery’ without the single quotes. Paging through the results, look for multiple instances of jQuery.js, jQuery.1.4.0.js, jQuery.1.8.3.min.js, or something similar. If you locate multiple inclusions of jQuery, you have probably uncovered the cause of your issues. Try to find which extensions are making the calls and deactivating them one by one. Once you find the culprit, feel free to email their support team asking them to fix their poor coding choices.
Known Errors & IssuesThe most recent request was denied because it contained an invalid security token.
This issue is most likely to be caused for the following 2 reasons.
- The Session Lifetime set in the Joomla! Global Configuration page is too low. Increasing the session lifetime will result in fewer "Invalid token" messages for legitimate users.
- If you have Joomla's Page Cache enabled then you might experience this error response. In most cases, disabling that plugin seems to fix the issue.
- If you're using Joomla Cache and you're loading the form with a module, try disabling module's Caching option.
You're probably facing a PHP fatal error caused by a 3rd party Joomla! extension. Enable Error Reporting through Joomla configuration page, submit the form once again and see if the form reports any PHP errors.The Ajax Interface component is missing or is not enabled
