WordPress: Could not save password reset key to database
If you have the error “Could not save password reset key to database.”, more than likely you have one of the following issues:
- Database server is full (the values cannot be saved to the database due to the file system being 100% full)
- Database server is read-only (If you use a service such as Amazon Web Service’s RDS your website may be connecting to the read replica instead of the write server)
- Database cannot make changes to database tables (check the database files can be written to by the user the database service is running as)
- Temporary folder on your server is not writable (this is the least likely scenario)
I found this problem is not documented well so I blogged my research. Hopefully this helps others searching for a solution.
