Error messages from Log In page, after hitting "Register" and "Lost Password" link - "" Unexpected error while performing an AJAX call. Maybe the connection to the server is lost."

I am receiving error messages from my Log In page, after hitting "Register" and "Lost Password" link (that is,  "http://sitedoamain.org/register" and "http://sitedoamain.org/forgotpassword" )

" Unexpected error while performing an AJAX call. Maybe the connection to the server is lost."

Please advise about possible causes and solutions. Thank you.

  • Problem is very likely caused by a bug in a 3rd party plugin or usage of a 3rd party plugin not compatible with the version of Elgg you use (e.g. not compatible with Elgg 2.0/2.1) or not using the latest version of Elgg core (i.e. latest 1.12 or 2.1 version of Elgg).

    If you are not using the latest Elgg version (either latest 1.12 or 2.1) update Elgg core. If the issue is not fixed then, check for outdated plugin (either update such plugins or don't use them if they are not compatible with the version of Elgg you use). If you're not sure what plugin causes the issue, disable all 3rd party plugins to see if the issue still appears (if yes it wouldn't be a plugin issue). If not, enable the plugins one by one to find out the problematic plugin.
