error 503 in backend
Hi there from yesterday I can't log into my websiste backend
witradeconsulting.it/wp-admin (Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.)
The frontend apparently it seems to be okay but it doesnt't work:
ex. if I try to fill the form in the contact page (https://www.witradeconsulting.it/registrazione/) it doesn't process the request, if I try to do a purchase it doesn't work
I tried to deactivate all the plugin using filezilla but it doesn't fix it, if I disabled Betheme the problem disappear and I can regularly log into the backend,.
How can I fix it?
Thank's in advance,
