Title: Fatal PHP error Last modified: August 8, 2022 --- # Fatal PHP error * [Erwin](https://wordpress.org/support/users/baksteen/) * (@baksteen) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/) * I get a bunch of PHP errors and a final Fatal Error when viewing the events calendar page, the new V2 one. V1 works fine.

Doing a search on the unserializer error leads me to quite a few other site’s events calendar pages. * More info: the Notice errors don’t always appear. Mostly when going from one page to another.

Dont get me wrong we want to get to that bug and resolve but it ends up not bring on top of our priority list. * best Regards, * Thread Starter [Erwin](https://wordpress.org/support/users/baksteen/) * (@baksteen) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15420730) * Heya, * Thanks for the fast response. Here’s what I did: I updated the events by pressing the update button. I don’t know if that’s enough? I don’t know which events cause the issue. How can I find out? What should I do to fix these events? * I changed and saved the permalink structure. * I don’t know how to clear transients. * I saved the event settings. I have only been using the events plugin on this site for about a week. * I’ve never used the V1 view before so I didn’t switch from legacy to V2 as far as I know. * Plugin Author [Gustavo Bordoni](https://wordpress.org/support/users/bordoni/) * (@bordoni) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15420988) * Uhnn I see, * This plugin “Transient Manager” is the best way to handle some of these problems. * [https://wordpress.org/plugins/transients-manager/](https://wordpress.org/plugins/transients-manager/) * If you remove the Object caching plugin does the bug go away? * If yes, let me know and I can log the bug for our team to fix it. I can’t promise deadlines on that because there are tons of priorities. * But I can for sure make suggestions on other Caching plugins that would do the same job without the problems. * best regards, * Thread Starter [Erwin](https://wordpress.org/support/users/baksteen/) * (@baksteen) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15421338) * Heya, * The fast response is appreciated, thanks. * I have installed the transients manager, deleted everything but could still reproduce the errors the same way as before. * After disabling Redis/Object Cache Pro, I could not reproduce the errors anymore. * Cheers * Plugin Author [Gustavo Bordoni](https://wordpress.org/support/users/bordoni/) * (@bordoni) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15421401) * That is not super good, as caching plugins can be important. * Since this is a Premium plugin we dont have access to the codebase just yet. * If you dont mind reaching out to us on: * [https://theeventscalendar.com/support/](https://theeventscalendar.com/support/) * And sharing the plugin zip that is causing the problem it would be amazing. * Specifically ask people to make sure the ZIP finds me you can use my name and link to this thread. * Once we have a Ticket registered on our Bug Tracker I will post here a reference you can use to track when the bug is resolved. * Best Regards, * Thread Starter [Erwin](https://wordpress.org/support/users/baksteen/) * (@baksteen) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15421544) * Thanks again for the reply.

It’s still not solved, and it’s been almost 3 months. * I don’t want to sound impatient, but 3 months is a bit long. I don’t want to switch to another caching plugin. Redis is fine. It’s the default caching from Cloudways (not a small player in the field). * Surely, you have your priorities, but I’d rather switch to a different events plugin than to switch to another caching plugin, since Redis is integrated and optimized and all. * Cheers * Plugin Support [WilloftheD](https://wordpress.org/support/users/abzlevelup/) * (@abzlevelup) * [4 years ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15669150) * Hi [@baksteen](https://wordpress.org/support/users/baksteen/) [@umbc](https://wordpress.org/support/users/umbc/) [@cpiechotta](https://wordpress.org/support/users/cpiechotta/), our devs are still working on a fix, since there are a lot of things to consider in fixing the compatibility issue with Redis. I checked, the bug ticket is still in progress. Rest assured that we’ll be releasing the fix as soon as it is ready. * I really do understand your frustrations and I know this is not a sufficient answer, but I do think it is better to be honest. Apologies for the inconvenience and having to experience this delay — I would keep this thread open. * We appreciate your time and patience. * Best, Abz * ________________________ * Internal Bug Ticket Reference: TEC-4351 * Thread Starter [Erwin](https://wordpress.org/support/users/baksteen/) * (@baksteen) * [4 years ago](https://wordpress.org/support/topic/fatal-php-error-25/#post-15669157) * [@abzlevelup](https://wordpress.org/support/users/abzlevelup/) ok, thanks for the update.

I can enable Object Cache Pro on my Cloudways hosted website, and the Events Calendar events page stops loading and renders a blank page. After I disable Object Cache Pro, the page renders. * All the rest of the site pages render properly.
