call_user_func() error in Lazy_String.php

Hi @studiomondiale ,

Thanks for reaching out.

Could you try configuring your W3 Total Cache based on the settings described on our knowledgebase article here and check if that makes a difference?

If that doesn’t help, could you provide the version of the following? This will help me understand how your system is set up.

• PHP
• WordPress
• The Events Calendar
• Theme

I have the same issue with one of my website. I followed your recommendations regarding caching with W3 Total Cache, but the only solution was to deactivate “Object Caching” despite “Object caching greatly increases performance for highly dynamic sites that use the Object Cache API.”

Do you have any tips to fix this issue ?

Hello,

Thanks for your reply, @d0153.

I’m afraid it’s the same situation that @atomystik describes, the only solution right now is to disable object caching in W3TC ??

This is my setup:
PHP 7.3.23 (I know it’s outdated)
WordPress 6.1.1
TEC 6.0.7.1
Enfold Theme

Hi @studiomondiale @atomystik

There could be a plugin/theme conflict on your end. Could you try running a conflict test and check if that makes a difference??I suggest conducting these tests on a Staging Server.

Let me know how it goes.

There was no conflict with another Theme or plugin (from what I’ve seeing). But I found a way to deactivate “Object cache” for Events Calendar in W3TC by adding these 2 groups in “Performance > Object Cache > Advanced > Non-persistent groups” :
tribe-events-non-persistent
tribe-events

So I can keep using Object Cache for the website and dont cache objects for Events Calendar.
Hope this will help.

Hi @studiomondiale @atomystik

Just to confirm, the issue persists even if only our plugins are active and you’re using a default theme (e.g. 2020 theme)? If so, please provide a staging site URL where the issue shows so we can check it further on our end.

@atomystik Thank you for providing your workaround on this issue.
