I can't update from 5.3.9 to 5.3.10. If I update locally using Mamp Pro, I get the unpacked listing appear with the 'update' button, then after clicking the update button, eventually I get a "Data Saved" prompt, which disappears and I'm still at the 'Update' page in the settings screen..
If I then click 'Settings' and scroll to the bottom, it still says I'm on version 5.3.9 - and doesn't appear to have updated.
If I do it on my remote test site, I get the unpacked listing with the update button, but clicking update results in a 504 Gateway Timeout error.
I'm not going to install it on my clients live site until I know what's going on.. any idea why the built in update isn't working?
