Is this a Hosting Problem?

Hi,

I have a Reseller hosting account with just my own twelve WP sites on, as I like a separate Cpanel for each.

But every time I use CCleaner or delete cookies, I cannot log in at: domain.com/wp-admin. And I cannot choose the Lost Password option either . There is no way into the dashboard at all.

It always adds a silly long bunch of characters on the URL, like this:



https: //domain.com/wp-login.php?redirect_to=https%3A%2F%2Fdomain.com%2Fw p-admin%2Fupload.php&reauth=1




I contacted my host twice before (Stablehost) and they fixed it within minutes, saying I wasn't putting .php on the end. (I was. I was trying every combination ...so they must have done somethng on the server and weren't telling me.)

But if I use CCleaner again it happens again. It's now happened to ALL my sites, and I am sick of contacting my host every week.

I need a permanent fix; not a temporary one.

I read recently that cheap hosting always costs in the end. I only pay $9.95 on the Reseller account so I know it's very cheap.

And they've been great for several years but since I left them a glowing 5 star review, I've had to contact them every week.

Is this a coincidence? Or did they think they no longer have to please me, now they have a great review, so they can mess with my sites? (Silly I know, but I don't know what to think. I know nothing about the tech side of hosting).

Can anyone tell me if this is this a Hosting issue?

And does anyone know how I can solve it permanently (preferably using File Manager), without changing hosting company yet?

Thank you


UPDATE: I have now found out it is NOT related to cookies or CCleaner. Because the sites were not working earlier and now they are OK, and I haven't touched cookies or CCleaner.

Still don't know what caused it, but I can work for now.
