I have another issues with my website, i'll be as simple as possible :

Firstly, to join my oxwall platform, the captcha is now impossible to read. I've seen other topics but it seems to be different as the solution was given for a disappeared captcha.

Then, after the update, no data was erased, which surprised me, including my CSS custom code. But now it appears in admin/theme/css but doesn't show up in the page with which it's related.

Any help ?

Thank you.
