So possibly a corrupt DB table or config file. * Thanks for getting back to me, * Mark - This reply was modified 6 years, 3 months ago by [mkcn](https://wordpress.org/support/users/mkcn/).

The third resulted in: * `Fatal error: Out of memory (allocated 174063616) (tried to allocate 217088 bytes) in */wp-db.php on line 1972 The site is experiencing technical difficulties` * I have asked 123-Reg for help on this one. * I’ll leave the scan settings as they are on the first two and see what happens overnight. 123-Reg support stated that their system is triggered to update Wordfence settings if a scan exceeds 3 minutes. - This reply was modified 6 years, 11 months ago by [mkcn](https://wordpress.org/support/users/mkcn/). - This reply was modified 6 years, 11 months ago by [mkcn](https://wordpress.org/support/users/mkcn/). * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Wordfence Security - Firewall, Malware Scan, and Login Security] Performance options reset by host](https://wordpress.org/support/topic/performance-options-reset-by-host-2/) * Thread Starter [mkcn](https://wordpress.org/support/users/mkcn/) * (@mkcn) * [6 years, 11 months ago](https://wordpress.org/support/topic/performance-options-reset-by-host-2/#post-11567830) * Hi [@singingcyclist](https://wordpress.org/support/users/singingcyclist/) – that’s interesting that your scans are running fine, thanks for letting me know that. * I have now come across the following suggested settings is in a separate topic that you posted on: * ``` Maximum execution time for each scan stage: 15 Time limit that a scan can run in seconds: 0 ``` * Did you try this? * Looks like that’ll be the next thing I try to see if a “standard” scan will work within the allocated 3 minutes. All my “standard” scans are switching to “limited” overnight. Viewing 6 replies - 1 through 6 (of 6 total)
