Hi @vbsa,
The error message “The form was unable to submit. Please contact the site administrator.” can appear if there are some JavaScript (JS) errors on your site or the form token that is used for Anti-spam protection (https://a.supportally.com/GhUYkC) are cached by some caching plugins you’re using. The form tokens are valid for 48 hours, so if you have a page cached for more than that, the form tokens become invalid and the form won’t be able to submit. If you have any optimization or caching plugins, you might want to check the cache lifespan and decrease them.
You could also quickly check this by clearing your cache, then running a test submission. If the from is able to submit after the cache has been freshly cleared, it confirms that caching is the issue.
While testing, please ensure that you test from a browser that isn’t logged in to your site, because it is common for caching plugins to not cache logged in users. With the cache being circumvented, the issue wouldn’t be able to present itself (if it is the cache).
A broader test would be to disable any caching/optimization plugins you have active on your site.
Please let me know how it goes ??
Kindly,
