Ok, i can provide some help, only if you are willing to try, without interrupting your website.
Did the plugin for bot blackhole helped at all?
Do you have ANY statistics for your plan or server, like resources usage? So we can be sure it is a database issue as your support told you?
Is any BACKUP service running automatically or manually each day?
Im not sure if BHFBB worked, seems no different.Â
I can get all stats for my site in my cpanle to see whats been used
And there is no back up, but i have (had, just disabled them) Brooken links checker, and revivie old posts, with pro add onÂ
Maybe thats whats been causing the issue all along? Completely over looked the broken link checker. If that is crawling the site for links everyday, it could be that?
Seems to be a database issue mate yes. My site is not even online this moringin, it says error establishing database connection or something like this.Â
I have other sites on the same server, and they work fine, it is just my forum site that is having issues..... I have my host looking into it now to see if we can find the cause.... again lol
This is what my host said:
No, the issue is with the database max connection and our admins are checking further with this.
Our admins have increased the Max connections and website https://percysgrowroom.com/  is loading fine now. Please check and confirm it from your end.
user notification, yes
user notification live update, no
