apply_filters in template crashes browser

[freshdevelop]

[WP v. 4.1.3 - Pods v. 2.5.1.2]

So I discovered that {@post_content} does not work, so I am using $obj->field('post_content') to print the post content in template. Moreover, when I try to apply filters, like by using

field('post_content')); ?>

firefox crashes.

Something doesn't add up here, {@post_content} should be working and running the_content filter on it already.

Beyond that, I'm not sure what's going on here with the crashing, what other plugins do you have activated?

[freshdevelop]

Can confirm. {@post_content} makes my page loading in loop and ultimately going "blank". Calling the_content filter directly crashes the whole browser. I managed to make it work in some way by using field('post_content')); ?>

I'm using not so many plugins other than Pods (SiteOrigin's Page Builder, LayerSlider). I'd try to disable everything other than this but I'm working in a semi-production setup.

I'll check soon on a clean install and let you know.

It sounds like there's an infinite loop going on here with the_content, some plugin may be hooking into it but not removing / disabling itself so it continues to process additional the_content calls embedded within.

The infinite loop is caused by the apply_filters() function.
Page Builder already called apply_filters() function, it is impossible to call again.

If you want to avoid using the apply_filter() function while displaying the well formatted content, you can use the wpautop() function with a content display function (like get_post_field or get_the_content ...).

[sc0ttkclark]

Best practice is to remove your filter at the start of your content filter function, then add it back at the end, to avoid recursion loops.

This solution with remove_filters() function does not work in my plugin (Modal-Portfolio), that's why I found another solution with wpautop() (which is called by apply_filters when we want to recover formatted content ...).
