Error 503 in the frontend

Hi, today the front end of my site went down.

Upon looking on every plugin and consulting my server service we encounter that this plugin was generating the issue.

I do need this plugin to use my site properly, so, can you please help me?

I can give you the info you need to repro the bug.

Please contact me as soon as you can.
