Calendar no longer loading. Getting a 404 error
I’m sorry to hear you are still experiencing those issues.
I’d be happy to help you troubleshoot the issue and hopefully find the source of the problem.
First, from your system information I can see that your WP_MEMORY_LIMIT is set to 128MB, which seems a little low since you have many plugins enabled. This could be causing the limit to be reached when navigating through some pages and thus throwing errors and preventing you or your users from navigating the site.
I recommend you try raising the memory limit for your WordPress installation and see if you still get the errors. You can learn how to do that here > https://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP
We always suggest to setup a dev/staging site so you can test things out and make all plugins, theme and WordPress core updates without disrupting the live site.
After that, try reproducing the issue a few times, so that in case there is an error, it will be saved into the debug.log file. Please share that log file with us so we can see if any problem from there.
Please let us know how it goes.
Hey there! This thread has been pretty quiet for the last three weeks, so we’re going to go ahead and close it to avoid confusion with other topics. If you’re still looking for help with this, please do open a new thread, reference this one and we’d be more than happy to continue the conversation over there.
Thanks so much!
