Adding any extension is redirecting

I think maybe the nameservers haven’t propagated totally? Did you change anything in the last 48 hours?

Go here, https://www.yougetsignal.com/tools/web-sites-on-web-server/ and check your site. You will see you are on a server with some possible x-rated siteous although it may be that your host is just cybersquatting on a bunch of names.

Hi

Thanks for your help.

That link gives me two examples highlighted in red.

I use Easypace as a host for my webspace. I have not made any changes recently and my portfolio link worked before.

Contact Easypace as it is their parking page coming up anytime there is a 404 error. That would explain the gibberish.

For the 404 error when you try to add something you can try
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
