Tabs open only blank screen

Hi.

This is the first time we’ve heard of a problem like this.

When you say “totally empty white page”, do mean not even the theme header and footer is appearing?

Are you running PHP >= 5.3?

Can you please send me a link to your website so that I may have a look?

Thanks for quick reply!

“Totally empty white page”, no theme headers or footers. There is nothing in page source even. I’m using PHP 5.6.16.

Website link to test the problem, it happens with both public and private tabs:

Thanks for the link.

Very strange indeed. Can you please activate WP Debug in your wp-config.php file and try again? At least then we’ll know what’s causing the error instead of a blank page.

I activated WP Debug, but can’t really myself say anything about it.

I don’t see any errors. Are you sure it’s activated?

Have you tried adding another tab to see if the same problem occurs?

Also, are you using any caching or “performance” plugins?

I have now in wp-config.php file this line, based on my understanding it should activate debugging, right?

define(‘WP_DEBUG’, true);

The profile page has 4 private tabs and added that one public tab for testing purposes. Also earlier tried to remove all tabs and create again. All tabs, both private and public, have same problem. “Native UM tabs”, Posts and Comments, are working correctly when tried to turn those on.

I have these plugin active, none of these should be performance/cache related I think:

Jetpack by WordPress.com

Ok, so debug is on… no errors then.

I really have no idea what the cause of this could be. I’ve never seen this behaviour before.

Perhaps try deleting and reinstalling the plugin.

Thanks for help but the problem remains. Tried delete/uninstall also. Need to figure out something else…

WP_DEBUG flag didn’t help as for some reason the error message didn’t show… but changing WP_DEBUG_LOG flag on helped to capture at least something, does this give you any clue what could be the problem?

Ok, so the problem is the PHP memory limit. Have you tried increasing your PHP limit in wp-config.php?

You can also use the P3 plugin profiler to see what plugins are using lots of resources.

I have already changed PHP memory from 128 to 256 but no effect:
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );

I tried to P3 profiler, but it gives only information about performance, didn’t give much help to track memory usage. Though P3 was pointing out that Jetpack plugin (needed by Sydney theme I use) and Polylang plugin are quite hungry for resources. But even deactivating both those, it doesn’t change help.

Ultimate Member “native tabs” Posts and Comments work just fine, but with or without having them visible in profile the added new tabs don’t work.

I have no idea whether this might work, but please change line 9 in the plugin’s core.php file to:

add_action('template_redirect', array($this, 'show_profile_tab_content'), 20);

Let’s see if that resolves the problem.

No, unfortunately nothing changed.

I’m pretty much all out of suggestions now. I’m guessing it’s a theme issue as we’ve had no other reports of a similar error.

Fortunately you can still easily add custom tabs without the plugin. There’s documentation on how to do this available on the UM website.

Sorry the plugin didn’t work for you.
