Hi @joseprn
I hope you’re well today!
I tested the form on your page and I can see the issue there. It’s certainly unexpected but I see it’s a “500 internal server error” and that means it’s quite a generic error that doesn’t really explain much.
Usually, it means that there’s some resource issues or a conflict with other code on site but it may as well be related e.g. to some misconfiguration of site or server (e.g. related to internal rewrites or to security settings). It’s rather hard to tell without more troubleshooting.
Most important steps at this moment would be to check WordPress debugging report and do a conflict test.
1. Debuggin
Please add following lines to the “wp-config.php” file of your site, right above the “/* That’s all, stop editing */” line:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
Once they are added, try submitting the form a few times and after that look into the file named “debug.log” in the /wp-content/ folder of your site. There should be some Fatal Errors (and probably warnings as well) logged so let us know about those.
After that you can remove above lines from the “wp-config.php” file.
2. A full conflict test:
a) take a full backup of the site just in case
b) temporarily switch theme to one of default themes such as e.g. Twenty Twenty-Four
c) temporarily disable all plugins except Forminator
Test the form and if at this point it results with the same issue/error, it means it’s not a conflict but is most likely related to some server security settings aspect or misconfiguration; you can skip the rest of the test and we’ll see what to do next to identify the problem.
If the form does work fine at this point
d) re-enable your original theme and check again
e) if it still works fine, start enabling your plugins back one-by-one after each one testing the from
At some point form stops working again so the last enabled plugin (or the theme) right before that will be our culprit – let us know about it and we’ll take it from there to test it in details and find a fix.
Kind regards,
Adam
