HTTP ERROR 500

Hello @cop96,

Can you give me a screenshot where this is happening?

Can you enable error reporting and error log from your wp-config.php and check what exactly is the error occuring?

Hello. Hi. Thank you for answering. I have just detected that the error is caused by the MBE (Mail Boxes ETC) plugin.

Glad you found the problem, Can you edit the page after you have deactivated the MBE plugin?

Yes, but the problem is that I need the mbe plugin to work as well. it’s possible?

This should be possible but you will have to contact the mbe plugin author to check the errors in the error log on your site.

They should be better at debugging this issue as this is coming from their code.
