Hello. Thank you for contacting the Toolset support.

Well - this is strange that it works for few forms and not working for other forms.

Is your CRED form using any CRED API? For instance, a cred_save_data hook or a cred_mail_headers hook?
- I would like to see if your WordPress installation is registering any errors. You can see how to enable debug logging here:
https://toolset.com/documentation/user-guides/debugging-toolset/

Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Then try to submit the CRED form where you encounter the errors and check your server log - do you see anything?

If any errors are generated, this will create an error_log.txt file in your site's root directory. Please share error_log errors with me.

Hi,
when I add in those lines the error stops. Please advise

Well - there is nothing related to the code lines I shared with you that should fix the AJAX issue. This looks like something from your server not working consistently.

Hi,
I dont agree with that it is to do with the server. As I stated already some forms with ajax submission have been working without error. I need this resolved urgently as it is a major issue for users.
Please help.

Well - you said with following reply that by adding the code lines I shared with you resolve the issue:

The fact is that, the code lines are related to activating WP_DEBUG and error log - I wonder how it fix your issue.

Did you follow the guidelines I gave with the following reply?

If yes:
Did you see anything in error log?
