Because of my internet host and the number of plugins I run on my blog, I get an "out of memory" error in WordPress each time I try to automatically upgrade my wordpress install from the admin pages.
Long story short, I run out of available memory because I am using a large amount of memory for the MySQL & PHP processes.
The good news is… there's a real simple work around that will allow you to automatically upgrade your WordPress version with very little effort.
Work Around for WordPress Out of Memory Errors on Upgrade
- Within WordPress admin, bulk select & disable all plugins.
- Perform the one click upgrade of your WordPress installation.
- Return to the plugin page & enable your plugins.
Again, this is just a workaround. Your milage may vary.
Oh… and one more thing. Always backup your WordPress installation before making upgrades. (Too lazy to upgrade? Use this plugin!)
