Wordpress LScache Plugin: esi shortcode with Caldera forms
Last Updated on: Wed, 15 Apr 2026 00:00:02 I am using Caldera Forms and have been getting the error message: Submission rejected, token invalid . I have tried adding the page name to the Exclude list, then purging the caches (browsers too) and retrying, but the error persists. I found a page telling how to modify Caldera forms to use ESI, but was hesitant to change a plugin that could be subsequently updated by Caldera. Then I thought about using the new [esi] shortcode in the LiteSpeed Cache plugin. When I changed the pages form shortcode from [caldera_form id= CF5a98693025f5f ] to [esi caldera_form id= CF5a98693025f5f ], the page now simply displays the original shortcode as text on the page (no form is displayed). What can I do to get the form working with caching? Thanks for your help. This topic was modified 3 years, 10 months ago by jlahm. The page I need help with: http://lifeinmotionresources.net/information/schedule Do you have ESI enabled in setting? Yes, I do have it enabled. However, I found the error and it was NOT due to the LiteSpeed cache. My original problem was caused by a conflict with using Plugin Organizer, and while I had the Caldera Form plugin enabled on the page, enabling Caldera site-wide seemed to be needed. I also found out that Caldera Forms has made their plugin ESI compliant and recommends adjusting the cache settings to expire in 10 hours. Using the ESI shortcode was not needed.
