WordPress admin login gives me blank page back (4 posts)

    Hi all I am having this problem with WordPress admin login and W3 Total Caching.

    Lets start from the beginning. When I visit the website it appears to be working just fine. When I try to login on the WordPress admin page it returns me a blank page. No errors nothing just a blank page.

    This is not the first time it happens, so I called my hostings provider to check if anything is going on with the servers. So we solved the problem last time by just rebooting the server. That worked website was running again and could login in to wp admin area.

    Now today same thing happens again. We did some research my hostings provider comes up with this error from wordpress.

    mod_fcgid: stderr: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 64 bytes) in /public_html/wp-includes/functions.php on line 3559

    I have no idea what this problem is and where it comes from.

    Probably this is not the only problem with this site. We are also using W3 Total Caching for this site. Are there any issue's know with this plug-in that can make the server do strange things?

    Kind regards

    This is usually a site issue - not a plugin specific one. Try increasing the memory available to PHP.

    When we can't access the backend any more the website is also blank. We don't see anything. Website only doesn't appear when we tried to login on backend then get a blank page and then try to view the website again.

    When we empty our browser cache the website is shown again and login page in wp admin is also viewable. Until you hit the login button on the login page. Then the same thing happens again, blank page for admin area, blank page for complete website.

    We also tried to increase the memory but that didn't help, we memory still runs full.

    Try:
    - switching to the default theme by renaming your current theme's folder inside wp-content/themes and adding "-old" to the end of the folder name using FTP or whatever file management application your host provides.

    - resetting the plugins folder by FTP or phpMyAdmin.
