I installed odoo18 communityt. I have a problem with themes ,any theme I upload to install won't install(no activate button) I even tried ensuring the state of the theme is 'not installed'(enforced by code) when I did that , it shows the activate button but when pressed it displays "cancel install" button and does not install the theme, What can I do , because I checked some of the themes on my local instance and they are installable. I've been stuck here for a while please assist.How it displays themes (code Backend - on the left ,after uploading the theme, does not show activation button), (Jazzy theme on the right I enforced it to have activation state and after installing it, it shows that)
