 * Just installing Hummingbird breaks my site!
 * I get the following error message appearing at the bottom of my WooCommerce cart
   page: “Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
   allocate 238015 bytes) in *****/wp-content/plugins/hummingbird-performance/core/
   modules/minify/class-minify-group.php on line 1150”
 * That stops the page loading and leaves visitors stuck in a vortex of doom, requiring
   them to close the browser window in order to get out!
 * This occurs before making any alterations at all. I only have to activate the
   plugin and this error appears.
 * The server is Apache on Linux, I’m using the Divi theme from Elegant Themes, 
   and all my plugins etc. are up to date.

 * Hello [@sarahdfly](https://wordpress.org/support/users/sarahdfly/),
 * I’m sorry you are having this issue.
 * I believe what’s causing this issue is your php memory_limit or max_execution_time.
   Please follow these steps.
    1. Access your site via FTP or cPanel File Manager.
   2. In the web root of your site domain, create a new file. The file can be named**
   test.php**. 3. Inside the file, paste this code.
 *     ```
       <?php
       phpinfo();
       ?>
       ```
   
 * 4. Now go to domain.com/test.php.
    5. Search for the values **memory_limit** 
   and **max_execution_time**.
 * Could you please post those in a reply back to me? Also which web host are you
   currently with?
 * Looking forward to you’re reply.
 * Thanks,
    Alex 🙂

 * Hello [@sarahdfly](https://wordpress.org/support/users/sarahdfly/),
 * Okay. What we need to do from here is keep increasing the memory_limit until 
   the error goes away. I recommend raising the php **memory_limit** to **256M**
   and the **max_execution_time** to **125**. You may contact your web host to make
   the change for you or you can follow along with this article.

 * If your host does not allow limits as high as I specified above, I would set 
   them as high as your host allows.
 * If you are still facing the error after raising the limits be sure to check domain.
   com/test.php to make sure the changes took effect.
 * Can’t wait to hear back.
 * Thanks,
    Alex 🙂
