Hi Trevor / joncoux,
As promised I will be releasing a new version (v1.4) in the next 2 – 3 weeks which will return the ability to use a user-selected logo image.
Regarding the issue with saving Custom Text, another customer ran into the same thing and realized the the .txt files had somehow become read-only.
Assuming you have osTicket installed into a directory called /support, on a Linux server the solution will look something like this:
# chmod -R +w /support/osta/themes/css
