It seems loading form in iframe violates cross origin policy… Viewing 3 replies - 1 through 3 (of 3 total) * Thread Starter [pitajpetru](https://wordpress.org/support/users/pitajpetru/) * (@pitajpetru) * [4 years, 4 months ago](https://wordpress.org/support/topic/error-loading-forms/#post-15332653) * PHP Fatal error: Uncaught Error: Class name must be a valid object or a string in /home/pitaihgt/public_html/wp-content/plugins/give/src/Form/Templates.php: 120 Stack trace: #0 /home/pitaihgt/public_html/wp-content/plugins/give/src/Form/ Templates.php(104): Give\Form\Templates->getTemplateObject(NULL) #1 /home/pitaihgt/ public_html/wp-content/plugins/give/src/Controller/Form.php(306): Give\Form\Templates- >getTemplate() #2 /home/pitaihgt/public_html/wp-includes/class-wp-hook.php(309): Give\Controller\Form->handleOffSiteCheckoutRedirect(‘ [https://pitajpe…’](https://pitajpe…’);)# 3 /home/pitaihgt/public_html/wp-includes/plugin.php(189): WP_Hook->apply_filters(‘ [https://pitajpe…’](https://pitajpe…’);, Array) #4 /home/pitaihgt/public_html/ wp-includes/pluggable.php(1316): apply_filters(‘wp_redirect’, ‘ [https://pitajpe…’](https://pitajpe…’);, 301) #5 /home/pitaihgt/public_html/wp-includes/canonical.php(799): wp_redirect(‘ [https://pitajpe…’](https://pitajpe…’);, 301) #6 /home/pitaihgt/public_html/ wp-includes/class-wp-hook.php(307): redirect_canonical(‘ [https://pitajpe…’](https://pitajpe…’);)# 7 /home/pitaihgt/public_html/wp-includes/c in /home/pitaihgt/public_html/wp-content/ plugins/give/src/Form/Templates.php on line 120 * Plugin Support [Rick Alday](https://wordpress.org/support/users/mrdaro/) * (@mrdaro) * [4 years, 3 months ago](https://wordpress.org/support/topic/error-loading-forms/#post-15372177) * Hi [@pitajpetru](https://wordpress.org/support/users/pitajpetru/), * Glad you reached out here. * 99% of the time that error is caused by caching. * In order to verify that my hypothesis is right here, we need to exclude any asset loaded by GiveWP from the cache. * Caching is handled differently on various sites and web hosts, and most of them allow for excluding specific URLs or parts of URLs from caching. At the very least, you should exclude the following slugs from caching: /donations/ /donation- confirmation/ /donor-dashboard/ * Also, the following query strings: give-embed=donor-dashboard giveDonationFormInIframe =1 * Your host or the caching plugin/solution you are using can help with that. Some of them may require what’s called a “wildcard” like /donations/* to capture all subdirectories under the /donations/ folder. * You can also temporarily disable caching on the site to confirm that the uncached site isn’t showing the problem. * While fine-tuning cache falls outside the scope of the support we’re able to provide, your success with online donations is our number one priority, and we’re happy to provide any tips. * Thread Starter [pitajpetru](https://wordpress.org/support/users/pitajpetru/) * (@pitajpetru) * [4 years, 3 months ago](https://wordpress.org/support/topic/error-loading-forms/#post-15372342) * I guess you were right, error fixed itself couple of days after… * Classic form works correctly now! * Thanks Viewing 3 replies - 1 through 3 (of 3 total) The topic ‘Error loading forms’ is closed to new replies. * ![](https://ps.w.org/give/assets/icon-256x256.jpg?rev=2873287) * [GiveWP - Donation Plugin and Fundraising Platform](https://wordpress.org/plugins/give/) * [Frequently Asked Questions](https://wordpress.org/plugins/give/#faq) * [Support Threads](https://wordpress.org/support/plugin/give/) * [Active Topics](https://wordpress.org/support/plugin/give/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/give/unresolved/) * [Reviews](https://wordpress.org/support/plugin/give/reviews/) * 3 replies * 2 participants * Last reply from: [pitajpetru](https://wordpress.org/support/users/pitajpetru/) * Last activity: [4 years, 3 months ago](https://wordpress.org/support/topic/error-loading-forms/#post-15372342) * Status: resolved
