I have a small WordPress website with latest version of WP 6.1.
I update all plugin regularly and since yesterday i am not able to update any plugin as updates fails each time with below error
After this website gets stuck in Maintenance mode for about 10 minutes, which i fix by removing .maintenance file.
I have tried to update plugin several times in last 24 hours but i face same problem all the time.
I also tried turned off this setting define( 'WP_INSTALLING', false); based on one article without any relief.
upon checking log file error_log file it shows last log error from 15 Feb 23
[15-Feb-2023 16:46:38 UTC] Cron reschedule event error for hook: put_do_weekly_action, Error code: invalid_schedule, Error message: Event schedule does not exist., Data: {"schedule":"monthly","args":[],"interval":2635200}
I am a basic user of WP CMS any pointer to resolve this problem.
I am not sure also where i can find details related to Plugin update log
Update:
- I tried restoring old database backup that didn't solve the problem
- I tried restoring restoring all file but kept the latest DB that didn't solve the problem
Solution: When i restored full backup (database & files) in new different folder & then restored latest copy of database then only i was able to update all plugins without any problem.
It seems some file was corrupt which was causing the problem which i was not able to point as no error was logged.
