Update 5.3.7 – All posts broken!

Please be aware of the following problem with the recent update of the meow-lightbox and meow-gallery!
After the plugin update 2 days ago nearly all my blog-posts containing many galleries each (using different layouts) were completely broken. Nothing was shown anymore, except some header-image and a first paragraph. In the wordpress editor everything looked fine. Just the pages could not be build up anymore for the normal viewing mode.

Spending many, many hours I found that inactivating the meow-lightbox or the meow-gallery plugin completely restored all my posts. Of course, without the lightbox, each images will be opened on its own. This is still better than seeing nothing at all anymore.

Now I am searching for a different lightbox which might work with meow-gallery until the meow-lightbox will be fixed. The galleries itself work, just not with the last version of the lightbox.

Please fix the plugin. Version 5.3.6 was working fine so far.
