Fox contact no longer forwards my emails and no longer displays form error messa

Hello to you,
Fox contact no longer forwards my emails and no longer displays form error messages.
I tested the form empty of all mandatory information and nothing happens.
My version of joomla: 3.9.25
My PHP version: 7.4.15
My Fox contact version: 3.9.8
Accommodation: OVH
I manage other sites with exactly the same configuration without any problems.
Is there a solution?
Thank you in advance.

Hi,
I have exactly the same issue with two web sites hosted by Oxito.

The current PHP version for those two web sites is 7.2 and Fox Contact is working fine.

As PHP 7.2 is now completely outdated, I would like to switch to PHP 7.4, but with PHP 7.4, Fox Contact don't send any emails anymore and I had to switch back to PHP 7.2...

Joomla 3.9.26
Fox Contact 3.9.8

Did you already got an answer or solution ?

Thanks in advance.

I have found the solution to the problem:
1 - Go to: Configuration - site settings and then activate the 4 SEO settings
2 - Purge the joomla cache
And that's all!
