I recently installed this amazing plugin. after playing around some time, i saw, it has saved me from installing login lockout, db backup, firewall, blocking bad queries etc plugins. But i have faced some problems when i activated the basic and advanced firewall settings. It got conflicted with W3 super cache minify settings. Show 404 error in almost every post http://engineeringbookspdf.com/c/murachs-c-2010
Now i am removing the added lines from .htaccess file. Another error happens when trying to make a DB backup. It shows error like this
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 71 bytes) in /home/jyo******/public_html/wp-includes/wp-db.php on line 1542
What should i do to fix the backup problem?
