Error On Line 506 In Options.php

Hi,

Have you recently installed any new plugins? If you have try deactivating them and see if this error disappears. Let me know if this resolves the issue.

If you’re seeing this error either suddenly (no specific task was done to cause the error) or frequently, try deactivating all plugins to rule-out a plugin-specific issue and try switching themes to rule-out a theme-specific issue.

Otherwise, here are three ways to increase PHP’s memory allocation:

1. If you can edit or override the system php.ini file, increase the memory limit. For example, memory_limit = 128M

2. If you cannot edit or override the system php.ini file, add php_value memory_limit 128M to your .htaccess file.

3. If neither of these work, it’s time to ask your hosting provider to temporarily increase PHP’s memory allocation on your account.

(in the above examples, the limit is set to 128MB)

i have not installed any new plugins in over a month. I tried the deactivate all plugins and it still occurs. I changed themes and it still happens. I am currently on a VPS with 8 gigs of system memory. I have 2014mb allocated to wordpress to use.
I am running 32 plugins on this site and getting around 12k hits a day. The server never misses anything on the front end and rarely uses above 30% of resources even when the site has 50+ people on it at one time. I only get these errors on the dashboard when I am formatting posts. There are also two other editors that work on the site at the same time and they are getting the same thing. One seems to get it worse than myself or the other editor as He says he has to refresh the page sometimes 15 times before it brings him back to the editor screen. Should I try and up the wordpress available memory even more?
