A very common error for wordpress based blog / site whenever you modified
something inside pluginsis to receive empty page screen on user visit.
This error often is because of any installed WordPress caching plugins like
WP SUPER CACHE
W3 TOTAL CACHE.
causing the troubles.
If this doesn't fix the error and you need to Debug what is causing the odd
Empty pages.
Open wp-config.php and somewhere near beginning of file include:
define( 'WP_DEBUG', true);
After saving wp-config.php and refreshing WP size in Browser
(after cleaning browser cache)
Fatal error: Allowed memory size of 8388608 bytes exhausted
(tried to allocate 252212 bytes) in
/var/www/blog/wp-includes/cache.php on line 4
(tried to allocate 252212 bytes) in
/var/www/blog/wp-includes/cache.php on line 4
This is due to set maximum System Wide memory Limit of PHP Scripts to 8MB.
in it line:
define
('WP_MEMORY_LIMIT', '64M');That's all WordPress should be working normal again.
Enjoy 🙂
