Message about Network error

We are on v8.2.2, and lately the following error message keeps showing up periodically:

Network error Cannot read property ‘indexOf’ of null

Seems harmless for now as nothing seems broken yet. Does anyone know the cause of this? Thanks.

you could try to clear your cache, found in <pydio>/data/cache
and then rm -rf plugins_* and you could also clear the int cache, <pydio>/data/cache/i18n/*.

Thanks for the tip. Shortly after I made the post, I finally decided to install Pydio Booster which hasn’t been done yet in the past. And after that was set up I haven’t seen this error message. If it shows up again I’ll try to clear cache as you suggested.
