I looked into this, and it’s technically a problem in some other application (though I don’t have the information to know which one.

Some other plug-in is using the ‘previous_post_link’ filter without passing all of the arguments into it, and that causes My Calendar to get it with missing arguments.

I can make a couple changes to most likely be able to ignore that, but you can get rid of the errors by disabling whatever is passing too few arguments into the filter. Unfortunately, I can’t tell you what that might be. I’ll get the changes made in My Calendar, though.

Hi Joe

My suspicions is that the issue is caused by my Theme, which is built using Themler https://themler.io/. If I preview the website using any other Theme the error goes away. Obviously if I turn the Themler plugin off I lose my Theme so that’s not the ideal option. I have already raised a support ticket with Themler but because their support it totally inferior to yours ?? they have not yet answered. I have however now added your comment above. Many thanks in advance on trying to counter the error. Have you got a timescale on when this ‘Fix’ might be available?

Cheers

Rich

Plausibly this weekend.

Hi

Themler are sill not responding. I may be forced to change the website to Elementor Pro but this will take time. In the meantime are you able to implement a fix please?

Cheers

Hi Joe

Problem solved. Replaced Themler with Elementor

Thanks for getting back to me

Solved

Glad to hear it!
