@NilsHolgerson @amitsolanki22Developing themes for osticket is a little complicated, because you have to change and overwrite core files. If you wan't to integrate some other mods or doing an update it becomes complicated. Now we have a solution for you: We have integrated vqmod in osticket 1.9.12 and 1.10. . Vqmod is a override engine, that allows you to modify core files via external files. This system is approved over years in opencart, a open source ecommerce system. We are developing extensions and mods for this shop system, too.Here's is the link to the original vqmod on github:https://github.com/vqmod/vqmodHere's is the link to the wiki with some examples how to use vqmod:https://github.com/vqmod/vqmod/wiki/ExamplesIf you like to disable or deinstall an extension or theme, you have only to add a additional character to the file extension or delete the file. From now it's more easier to develop and test for osticket.We have tested the integration now since two weeks and solved some minor issues. All themes and mods, developed by us, will be now integrated with vqmod.We will keep you informed and are working hard to get all the new things online!
