Firstly - a comment: The fact that there is no easy way to search within just one plugin on this forum for a solution renders it ineffective for those using the forum and inefficient for those contributing support.
My base problem is that every time I activate wp better security I start to get memory problems that initially manifest themselves by some crashed widget displays within the admin interface - e.g. on the better wp security dashboard itself, just below 'need help' on the right I get 'Fatal error: Out of memory...etc in class-simplepie.php'
I have, and wp better security reports, PHP Memory Usage: 20.7 MB
PHP Memory Limit: 256M. I also have define('WP_MEMORY_LIMIT', '128M'); set in my wp-config.php.
I am running wordpress 3.4.2. I have only 4 other plugins running. I have a tiny database as it is a new site. I am not not actively looking for changed files.
In other words, there is no reason on earth why I should be running out of memory, but every time I activate wp better security I do, and every time I deactivate WBS the problem goes away, so if WBS is not causing memory problems, it is behaving very much as though it were.
On top of that, after installing WBS I went in and made my WordPress admin area hidden. This worked OK at first - I checked I could still logon after the change, but the following morning the site was down and every attempt to logon redirected me back to the logon screen.
Because it was a live site I was not interested in lengthy investigation so just deleted everything, files and DB, re-installed and restored from backup. After the restore I could logon, and the homepage for the site displayed OK, but every other page gave a 404 error despite the pages being there and published. I then deactivated WBS and the problem went away - i.e. the site became available as normal.
Currently I am running WBS but with some options turned off (Like hiding the admin area) but I am still getting the memory problems. This means, for example, that if I want to make changes to my 'Wordpress SEO' settings, I have to de-activate WBS first, as otherwise I cannot see many of the 'Wordpress SEO' settings. After I have made changes I turn WBS back on - but then I get the out of memory issues again and the uncomfortable feeling that it makes the site less stable even if it is better protected security wise.
I really want to use WBS and use it to implement a thorough security regime, but I find that
a) the memory issues are troubling
b) the potential for self-injury is large
For now, I would be really grateful if someone could help me resolve the memory problems so I don't feel like I'm sailing in a leaky boat.
For info the 4 other plugins I am using are: WordPress SEO, SEO rank reporter, contact form 7 and really simple captcha.
I'm running on Apache / Linux on a VPS.
If you need any more info let me know.
