There is a problem with phpthumb cache :
Setting phpThumb Cache folder permissions Setting phpThumb Cache folder permissions UNSUCCESSFUL.
The same as before. And I don't know why.
I can access to the admin panel of Flexicontent, I have no longer the "post installation" task to update (surely due to you intervention

)
All seems good except the plugin - Image / Image Gallery -.
I can't upload an image, certainly due to this phpthumb cache error during installation.
I don't know if I have to create another topic for my plugin images problem.
If you have an idea... :oops:
Anyway, thank you a thousand times for your help.
