I’m currently on Joomla! 3.6.0
All other extensions updated to current versions.
Except JA Teline V version 1.0.8 and T3 2.5.5
PROBLEM
.1 Signed in and saw new updates for T3 and JA Teline V.
.2 Updated T3 successfully to 2.6.0
.3 Updated JA Teline V successfully to 1.0.9
.4 Custom.css file goes missing (custom file is located in the root css folder of the teline template)
SOLUTION
Rollback to 1.0.8
copied code from custom.css
update to 1.0.9
custom.css goes missing again
create new custom.css
paste in copied code
PS: In case this might help, I notice the title of the template in JA extension manager is "ja_teline_v". I’m guessing it should be "JA Teline V"
