Hi, i’m Roberto,
I have installed the newsletter plugin, configured the newsletter subscription page with newsletter short code, added some fields and then I tried to test the form and I got a white page with:
“Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at firstname.lastname@example.org to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.”
I also tried to set permission to the php files involved in the process but I got the same error.
What can I do? I thank you in advance for any help.
