We’ve been noticing some odd behaviour lately with field sets on one of our customer’s site.

As follows:

When trying to add / update some data for a template field set on a page the data is either:
– not saved and other data is removed.
– saved and other data is removed.

I am not seeing any errors in the web dev console and it is not consistent. I tested it on PC and Mac and on Chrome, Safari, Firefox and IE 11.

We’ve noticed if we change the order of the field sets on the page edit screen the problem goes away but we have also noticed that this is not consistent.

Any help would be greatly appreciated.

Hey there,

I think it’s likely this is related to your PHP settings, as I’ve certainly seen his before.

Try increasing the limit on your max_input_vars and post_max_size variables in your PHP configuration. max_input_vars in particular might need to be a bit higher, as PHP will truncate data if you have a lot of custom fields for one page.

Let me know how you go.

Thanks Travis.

I’ve updated the php.ini and I’m gonna have the client test it.

Fingers crossed…

Latest From the Blog

MasterPress 1.4.0 is now available

6th May 2024

This release has a focus on improving compatibility with PHP 8.2. The introduction of inheritance validation to PHP produced a lot of warnings when using MasterPress with PHP 8.2. I have updated most of the problematic code – but some code would have broken in previous PHP versions, so I have temporarily disabled inheritance validation… 

Plugin Requirements

MasterPress requires a minimum of WordPress version 4.9, MySQL 5.6, and PHP version 5.6.20.

We also recommend that PHP is configured to use a memory limit of 64MB per request (128MB may be required for sites with higher complexity).

This plug-in is not compatible with the WordPress.com hosted service.
