WP Backend broken after PP installation & activation

[JaegersNet]

Hi there,

i just made a fresh installation of podlove publisher. After enabling it the WP backend is stuck. Only the left menu is visible, the right area is grey - for every tested menu entry.

Frontend seems to work fine, except the WP menu bar, which is missing.

After deactivating Podlove Publisher everything's fine again.

PP Version 2.3.12 WP Version 4.5-3 DE

I switched to the TwentySixteen Template - without any effect I checked apache error logs - without any relevant error messages I checked wp-debug.log - two other plugins have issues, I disabled them without effect

Until I start disabling plugin by plugin... any idea?

Never heard of that issue before. Symptoms suggest a PHP error but that should appear in wp-debug.log when logging is enabled. Can you inspect the generated HTML of a broken page? Maybe it could be helpful to see where exactly it stops rendering.

Try setting both define( 'WP_DEBUG', true ); and define( 'WP_DEBUG_DISPLAY', true );.

Ok, did it.

After disabling the two plugins "nofollow and Socialauthorbio"

Still the same issue: Only the menu bar in WordPress backend.

Ah, that's the one. Piwik is using the Spyc library, which the Publisher is also using. The Publisher is already patched to handle this. You can replace the file above manually with a recent one and the issues should go away: https://github.com/mustangostang/spyc/blob/master/Spyc.php

Ok, fixed it. At least the backend is working again. Now I'll give Podlove Publisher a try;

Thanks!
