    Hi,
    When I have W3 Total Cache On the memory usage then doubles, I get a lot of out of memory errors and internal server errors.
    This does not happen with the plugin disabled.

    That’s expected with the current releases (but not future ones), can you increase the PHP memory limit using the .htaccess file?

    Hi Frederick,

    I too have issues, and our host (BlueHost) is throttling us heavy. W3TC has added a whole lot of content to my htaccess file. What should I add to increase memory, and where would I insert it (any tags involved?).

    Many thanks,

    You didn’t paste the error so I don’t know the exact memory site you need now, but for example you could add the following line to the top of .htaccess:

    php_value memory_limit 72M

    BINGO!!!!
    php_value memory_limit 72M is a key!

    Hi Frederick,

    Thanks for the reply. The errors were simply: “Analysis Error
    The page returned an error: 500 Internal Server Error”    .

    I also enabled Rocket in the CloudFlare settings and went through the rest of the settings and made some changes I thought were going to be helpful.

    So when I got your reply here, I immediately applied the solution. But before adding the line you gave me I ran a speed test:
    http://gtmetrix.com/reports/www.iamsignificant.ca/9oJB9R9y

    I then added the line to my htaccess file and uploaded it to the server. Running a new speed test, I got the above Internal Error message.

    I clicked to run the test again and this time it carried the test through, reporting:
    http://gtmetrix.com/reports/www.iamsignificant.ca/PFHmsf0U

    I raised the number to 128M and tested again, same error message, and then again I tried running the test successfully. Results:
    http://gtmetrix.com/reports/www.iamsignificant.ca/kxNoYOZf

    So your solution did something!

    When I look at the tests results, I find that before inserting the 72M code, the line “Enable gzip compression” was showing a grade of F 14. Now with the 72M specified, the grade is still at F 14. But using 128M brings that line at A 100. So I left the value of 128M since it gives a noticeable increase in the test results.

    Those are the little mysteries regular guys like me are thankful for brains like yours who can help us out, it may feel simple for coders, but not being one, I deeply value your help… :O)

    About CloudFlare: I do hope they will reward you for your contribution and how many people you turned their way…

    Many thanks for everything!

    Hi,
    php_value memory_limit 72M does not help me sorry,
    When I put this at the top of my .htaccess file I get a permanent ‘Internal Server Error’ until I remove it.
    My site is http://www.freefullvideosonline.com
    Any ideas please?

    @styzer, W3TC needs far less memory in the latest release. Please upgrade. About cloudflare, please mention that to them if you don’t mind. 🙂

    @wwinter86, please upgrade to reduce memory usage. As for the 500 error there, ask your host why that doesn’t work for you, it’s quite unique.
