[Bug / Issue] Uploading new header logo to All Styles get timeout error

[Maltair]

Edit Site / Header
Edit Site Logo
Upload a logo image
When I click "All Styles" / Save - Choose which style(s) to apply the logo to - I invariably get a timeout error.
However - even though I am getting a timeout error, it seems like the logo is still being uploaded to all styles. Or is it?

When I click "Current Style" / Save - it uploads with no timeout error.

If you have CSS stored in the database, it will take less time to make this update than if it is stored as files. So a workaround could be to move CSS to the database and then upload a logo to all styles. Once it is done, then move them back.

Another option is to remove the themes you are not using from the database to reduce the load. To do this, put your vBulletin 5 into debug mode and remove the visible theme along with its parent from the Style Manager. When you upgrade, you can delete the unused themes from /core/install/themes before running the upgrade to prevent them from being re-installed.
