I was getting an error and couldn’t log into WordPress. I contacted my hosting and they said it was my theme causing the issue. It’s a theme I bought from a good site but I deleted it since they said it was causing the issue. Now when I try to install a new theme the same error appears. The error says Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
It’s only happening now when I go to themes. I have the 2021 theme activated now (my hosting activated it for me). Does anyone know what could be causing the error message when I try to change to a new theme?
