Hello, whereinhull, & welcome.
Often what we do in situations like this is to temporarily ask folks to switch to a default theme (they begin w/the word ‘twenty’), & to deactivate all plugins, then try to login/post & see if the error resolves. If that works, then reactivate your theme & try again. If things go haywire, then your theme is the culprit. If things still work, reactivate plugins one by one, logging in/posting after each, until a plugin breaks things, at which point you’ve again found the culprit.
Could you please list for us the plugins you’re running? It does sound as though you may be running some sort of security/brute force limiting plugin.
If the above steps are ineffective please open your wp-config.php file & change WP_debug from ‘false’ to ‘true’. This is a security risk, so please change it back when you’re done. At that point, please try to make a post, save it, & see what, if any, errors you receive.
Additionally, there are often files called error.log or error_log in your WordPress folder as well as in the subfolders. You may wish to look through these for recent entries. Feel free to post these to your reply if you feel they might be relevant.
Lastly, in your hosting provider’s control panel, there may be an applet called error logs or similar, where you can read serverside errors that have been generated. These may be helpful. Please post them in your reply if you feel they could help us guide you toward a resolution.
i changed the theme and disabled every plugin so there was nothing 3rd party switched on and still got the same issues….
No idea what has happened, as said, it just started with nothing been changed..
My bruteforce plugin is Loginizer
I changed the config code to; define(‘WP_DEBUG’, true);
Once again I got the Oops! That page can’t be found.
The last log in the error logs was:
[17-May-2018 03:50:14 UTC] PHP Warning: Error while sending QUERY packet. PID=2308664 in /home/gbhitsco/public_html/wp-includes/wp-db.php on line 1924
That was before this started… the site has worked since then…
I’m totally at a loss 🙁 I don’t want to lost the site as it has 4640 post on it and a lot of work
Cheers

Hello, Carl. A couple things come to mind, but I’ve not yet had coffee, so take them w/whatever amount of salt you deem appropriate (& it should likely be copious). The first thing is please check on the size of your database. You may need to do this w/your host. If a database gets too big, some shared hosting companies limit your activity pretty severely. If your hosting provider has such, you may wish to run a tool to check your database for corruption & another to repair it if required. These would be in your hosting provider’s control panel.
2nd, did you see any error.log or error_log files in your file manager? Did they contain any entries?
Lastly, I would be prepared to offer you a staging site on my server. You could upload the site to it (including database) & see if these issues remain. If not, then we know it’s a hosting problem. If they do, then there is an entry in CPanel for errors that could be used to troubleshoot further. I’ve done this before w/tricky problems like this on the forums, & it’s usually turned out to be either a hosting or a database issue.
Hopefully this is sufficiently coherent despite my caffeine deprivation. I’m going to remedy that posthaste.
thanks for your help… all is resolved
there was a mod security rule triggered against my IP address (as ModSecurity is security feature installed on all shared server), I have bypassed those rules against the website to resolve this issue.
Then had the server updated to PHP7
Runs fine now and is about 10 times the speed
Carl
I was afraid that might be a problem, Carl, but when you said that even w/Mod_security turned off your post content wasn’t saving, then I got concerned about other issues. Glad you got it resolved.
