Are the ftp details ok? It says, that the username/password combo is incorrect.
Altough I’m not sure what the problem is yet, the server responds really, really slowly. Sometimes it doesn’t even load. The error 504 refers to web server issues. (I had experienced same issues)
A few minutes ago I got search results from the widget in a few seconds, after reloading I had to wait for a minute to get results, now it does not even load. (I’m getting 403 error right now)
I did some research, and wp experts say, that 10-15 plugins activated simultaniously can cause such issues, but I think there is something wrong with the service provider right now.
As a first step I would deactivate all the plugins and activate them one by one (starting with ajax search pro) to see how the plugins are related to server issues. If you cannot access your site, there is a way to deactivate them from mysql, by running the following sql statement on the database:
UPDATE wp_options SET option_value = '' WHERE option_name = 'active_plugins';
After I can connect to ftp, I will put a “return” statement to the ajax search plugin main file’s first line, to see if this is indeed caused by the search engine.
Try to get in touch with the service provider in the meantime, maybe they are having issues.Best,
