When I do make changes to my form in the backend, I get an error message like this:
Warning: fopen(/home/public_html/administrator/components/com_breezingforms/ajax_cache/ajaxsave_0_0.40857069558356207.txt) [function.fopen]: failed to open stream: No such file or directory in /home/public_html/libraries/joomla/filesystem/file.php on line 268 Catchable fatal error: Argument 2 passed to QuickMode::save() must be an array, null given, called in /home/public_html/administrator/components/com_breezingforms/admin/quickmode.php on line 42 and defined in /home/public_html/administrator/components/com_breezingforms/admin/quickmode.class.php on line 23
Check your form in a different browser. Does the same thing happen then?
If it happens in other browsers, too, then the problem could be that the folder
"/administrator/components/com_breezingforms/ajax_cache/" is not writable or that you need to activate the FTP layer in the Joomla global configuration settings, using the same login data you are using with your regular FTP client.
