The client is on goDaddy cpanel hosting.
The problem we are having is that the server is throwing a bunch of 404 errors. It seems like it always 404s for redirects (like https://3h5.b74.mytemp.website/user/ -> https://3h5.b74.mytemp.website/user/pages or after logging in). However if you refresh the 404 goes away and shows the content as expected. This is a minor inconvenience as there are only a few places with links that redirect in the admin.
The bigger problem is that after using the admin for a while all of the sudden pages that previously worked start to 404. I have no idea why. It can also start to affect front end pages and eventually can cause every page (front and admin) to 404. My workaround has been to work in an incognito window so that when it happens I can close the window, open a new one and log back in. If I don't the 404s get cached and I am unable to work on the site.
We've built a lot of sites in ProcessWire and have never seen 404s like this. We've also never tried to set one up on GoDaddy before.
I've done a lot of Googling and can't figure out the solution, except to see that other people have had some issues with GoDaddy hosting not playing nice with the .htaccess file (attached for reference and to maybe send to GoDaddy). I also read every post here about GoDaddy and 404 and nothing has helped. I've tried a bunch of things in the htaccess file such as "RewriteBase /" and turning ModSecurity off. I'm stumped!
Unfortunately I don't have direct access to GoDaddy client account (only cPanel) so I can't put in support tickets. I've asked the client to create one but thought it was worth checking in here to see if anyone else had a similar issue or has successfully set up a PW site on GoDaddy.
Thanks!
