Problems with htaccess rewrite and db backup

Some of the advanced firewall rules will definitely cause issues with some other plugins. It would really help us put together a guide or tune the firewall rules if you can tell use which firewall option cuased the issue (we have a few firewall features so if you can tell us which one then it will help us with the investigation).

The following error basically means that your server is running out of PHP RAM memory limit:

Fatal error: Allowed memory size of 268435456 bytes exhausted

How much PHP RAM memory do you have on your server? (your hosting company can answer this question if you don’t know it already).

It got conflicted with W3 super cache minify settings. Show 404 error in almost every post

We are currently investigating this issue. It would speed up our efforts even more if you can tell us which of the “advanced firewall rules” are causing your problem.

At first i applied all of your firewall setting for better protection but when i saw error then i revoked one by one until it got back to normal state. Now in there i have only trace and track, list of directory contents and proxy comment posting settings applied. All of the other basic firewall, bad query strings, 5G rules, Advance character string filter settings have to be withheld.
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
Isn’t it trying to allocate 71 bytes from my 268435456 bytes memory? I’m not a wordpress expert sorry if i being wrong.
In my PHP configuration memory limit is 128Mb and upload_max_filesize is 256Mb.
It would be nice if you guys could add a “Delete all records” button on failed login records page. last week i have faced more than 500 brute force attack. I had to go through 27 pages one by one and delete them all because it takes a lot of db memory.

Peter has worked out a tweak for the “Advance character string filter” firewall to work with W3 Total Cache plugin’s minify feature. He is also adding the “Delete all records” button for the failed login records table. It will come in the next version of this plugin.

That PHP error is definitely because your server is running out of memory (trust me on this ?? Here is a link to a post where you can see how other users had this exact same error:

We have released a new version that should address the other two issues mentioned earlier.

closing this topic down as the issues mentioned here have been addressed now.
