Service links modules automatically desactivated

Hello,

Thanks a lot for your pretty module. Actually, 3 submodules are activated: Service links, General services and Widget services.

I am facing a very strange issue that I have never seen before:
After enabling or disabling another contributed module, any one but not SL, the General services and Widget services submodules are automatically disabled, and I cannot enable them anymore via the UI. I have to deal with System table into DB: setting Status field value to 1 then clearing caches.

Any idea ?

Best.
