as mentioned with my previous topics I have problems with my WP admin backend.
– caching in backend
I still haven’t solved this caching issue… Now occurred the bug that I cannot add more than one image to Penci Slider and just one advert to AdRotate plugin.. I am sure there are more similar incidents with other plugins which I haven’t noticed yet.
I suppose or hope, just like you, this bug happens due to a “broken” plugin..
Is your suggestion to solve this to deactivate ALL plugins and then activate Penci Slider plugin and check if this problem still happens?
