Forms 500 Error on WPForms

Hi,

I have the problem that I get a 500 error when a form is filled out. Can you help me? The guys of "WPForms" wrote:

The contact form, however, will not submit for me. After submitting it shows a 500 Error (https://cl.ly/1T2O2r2y323n). I believe this is due to your web host running out of memory when processing the page/form entry - this is the most common cause of a 500 error. Usually this can be resolved by increasing the available memory limit for you site in the settings.

Thanks a lot
Claudius
