I am conducting a seafile upgrade from version 6.3.4 to version 7.0.5.
In the previous version, I made some GUI customizations in order to add more links to the bottom bar.
I did this by creating a folder (seafile/seahub-data/custom/templates) and add the changes in nav_footer.html.
After the upgrade, those customizations disappeared. After some researchs I found that the software is not working like before therefore this method is no longer valid.
I will be grateful if I receive any help.
