Title: Large Memory Usage and Internal Server Errors Last modified: August 20, 2016 --- # Large Memory Usage and Internal Server Errors * [Wwessex](https://wordpress.org/support/users/wwinter86/) * (@wwinter86) * [14 years, 10 months ago](https://wordpress.org/support/topic/large-memory-usage-and-internal-server-errors/) * 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.

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, * styzer * Plugin Contributor [Frederick Townes](https://wordpress.org/support/users/fredericktownes/) * (@fredericktownes) * [14 years, 10 months ago](https://wordpress.org/support/topic/large-memory-usage-and-internal-server-errors/#post-2192601) * 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` * [styzer](https://wordpress.org/support/users/styzer/) * (@styzer) * [14 years, 10 months ago](https://wordpress.org/support/topic/large-memory-usage-and-internal-server-errors/#post-2192602) * **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](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](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](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! * Regards, * Andre Lefebvre * Thread Starter [Wwessex](https://wordpress.org/support/users/wwinter86/) * (@wwinter86) * [14 years, 10 months ago](https://wordpress.org/support/topic/large-memory-usage-and-internal-server-errors/#post-2192621) * 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](http://www.freefullvideosonline.com) Any ideas please? * Plugin Contributor [Frederick Townes](https://wordpress.org/support/users/fredericktownes/) * (@fredericktownes) * [14 years, 8 months ago](https://wordpress.org/support/topic/large-memory-usage-and-internal-server-errors/#post-2192658) * [@styzer](https://wordpress.org/support/users/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](https://wordpress.org/support/users/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.
