I know I've been bugging in support about this but, Shop and Market are being really weird.

Shop: To deactivate and activate, I have to right click the link and then click "open link in new tab" which I think is really, REALLY stupid.

Market: I can't search anything. When type in [e. Head Texture 128 x 128], it won't load, it doesn't say anything, the page just stays the same.

Can someone please help me?

I have the most up to date Web Browser, but I still don't know why its not working. And for the Market, I use proper grammar, I type in Head Texture 128 x 128, still doesn't work.

Because “Head texture 128 x 128” is not the name of the item.
Try “head texture” instead.
And no, capitalization is irrelevant.

I can't search anything though.
