Title: Multisite Issues Last modified: August 21, 2016 --- # Multisite Issues * Resolved [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/) * Hi, * I’ve got the plugin working perfectly on the first site in a multi-site installation. * But now I’ve tried to use it with a second site and can’t get it working. Both sites use their own child themes that are built off of the same theme. * When you go to submit a form w/o ajax you get a blank page and the form doesn’t submit. * With ajax it doesn’t submit either. * Can you provide any advice? Thank you! * [http://wordpress.org/plugins/gravity-forms-pdf-extended/](http://wordpress.org/plugins/gravity-forms-pdf-extended/) Viewing 9 replies - 1 through 9 (of 9 total) * Thread Starter [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212715) * Forgot to mention, the plugin is activated on a site by site basis (not network activated). * Plugin Author [Jake Jackson](https://wordpress.org/support/users/blue-liquid-designs/) * (@blue-liquid-designs) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212921) * Hi Keith, * Please disable AJAX on your Gravity Form, set WP_DEBUG to true in your wp-config. php file and attempt to submit your form again. * You should get an error message that will give more information about the problem. * Thread Starter [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212971) * Hi, * I’m getting the following error: * Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 65536 bytes) in /home/DIRECTORY/public_html/wp-content/plugins/gravity-forms- pdf-extended/mPDF/classes/ttfontsuni.php on line 1787 * Plugin Author [Jake Jackson](https://wordpress.org/support/users/blue-liquid-designs/) * (@blue-liquid-designs) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212987) * Hi Keith, * You need to increase the memory allocated to your website. [We recommend 128MB](http://gravityformspdfextended.com/documentation-v3-x-x/requirements/) but with a multisite you may require more. * Thread Starter [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212989) * Hi, * Thanks for the reply. * I tried increasing the PHP limit in wp_config, but that didn’t seem to help. I’m not sure if my host will let me increase the PHP memory limit or not, I’ll contact them. * What I don’t understand is why it would work with one site on the multisite install, but not another site. * On one of the sites it works fine, all of the time. * On another, it is throwing the error and failing, all of the time. * The two sites are almost identical. They use the same parent theme, and child themes are almost identical as well. * Do you have any ideas for a workaround that wouldn’t require me to increase the memory limit in php.ini? * Thank you again for all of your help. * Plugin Author [Jake Jackson](https://wordpress.org/support/users/blue-liquid-designs/) * (@blue-liquid-designs) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212990) * The content being loaded and processed may take up more memory on the problem site. * We have a section in the documentation on [memory issues which may help](http://gravityformspdfextended.com/documentation-v3-x-x/troubleshooting/memory-problems/) but it is no substitute for increasing your memory allocation. * Thread Starter [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212991) * I will check out the documentation. * Thread Starter [Keith Aldrich](https://wordpress.org/support/users/keith-aldrich/) * (@keith-aldrich) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212997) * I contacted my host and they increased our PHP memory limit to 128 mb. * Everything seems to be working fine now. Thanks for your help! * Plugin Author [Jake Jackson](https://wordpress.org/support/users/blue-liquid-designs/) * (@blue-liquid-designs) * [12 years, 7 months ago](https://wordpress.org/support/topic/multisite-issues-7/#post-4212998) * Good to hear Keith.
