Hello, I have plugins and custom applications that are not compatible with IPB 4.5.0

I cannot update without those applications that are essential for the functioning of my website

The original developer who created these add-ons and applications has not connected for a long time so I have no contact with him.

My question, is it possible that another developer can update if I pass the plugins or apps to him? or do you need the source code?

Thank you

 

 

Another developer could recreate the application or plugin, or they may be able to adjust your existing app/plugin with the source code available to them (i.e. with FTP access to your server to work on it there).
