Another fatal error after update from 1.9.3 to 2.0.1

Hi,

How did you update? From the WordPress backend? Maybe you should try again. The class ‘PLL_Admin_Sync’ was there in v1.9.x and is still there in v2.0.x. Maybe the corresponding file was missing for some reasons.

I just upgraded 2 different sites on the same host, both with php 5.4.

1st : All ok.
2nd : White pages everywhere.

The Second site has been running Polylang much longer, and is running more plugins.

I’m not exactly sure where to go from here, at the moment. Open to suggestions.

Thanks

I am happy to tell you that the plugin is working, now. The reason of the error was just an incomplete download, as you suggested.

Many thanks again!

Looks like it’s a plugin conflict generating the PHP error: content-aware-sidebars

They worked perfectly together through 1.9.3

@philrp

For me it’s the same problem. I use the Content Aware Sidebars, also.

Polylang v2.0.1
Content Aware Sidebars v3.2.4

On my side works one or other plugin but not both simultaneously.

I went back to version Polylang v1.9.3 until it is fixed.

Hi!

The problem is the wpml-config.xml file of Content Aware Sidebars which is malformed.

Polylang 2.0.2 should not break anymore on a malformed wpml-config.xml file. It will just ignore it.

However, as the file is ignored, multilingual features of the corresponding plugin/theme will not work as expected.

People having WP_DEBUG set to true will see warnings.

Thanks Chouby, I deleted polylang folder and reuploded it, now it is working..
