At the moment no one give a decent reply because more detailed information is needed. Your post did not include looking at any error logs and that is where you will find what specific problems are occurring. Once that is known, suggestions can be made on what to do.
Hi Champs
Sorry i didn’t look at errors because i haven’t really had many to take note of. Ive really been going blind on this a bit. I have cPanel.net helping, but they don’t have any system problems. I have some mysql error logs too, ill just put them in the next post.
Here’s the latest of them. Although the error connecting to the database was daily for the last how many days. Many.

Errors you provided are from June 10 and 6. If you have no errors with today’s date then problems are intermittent. That could mean problems occur when server is temporarily under a heavy load such as Bot attack.
Presuming you already have some security directives in your .htaccess and some security plugins, two plugins I recommend are:

https://wordpress.org/plugins/limit-login-attempts-reloaded/
