all the modules are gone. why this issue has been not discussed here yet?
it's like modulargrid is currently broken. why is that?

ok i deactivated my Adblocker and it works again. but i don't like that at all. this must be new

We did not change a thing. I guess there was an update for your Adblocker that decided that MG is no trustable resource anymore :(
Other users report issues with adblockers too. Which adblocker are you using?

the addblocker i use is calles addblocker lol (that most popular one). for chrome and FF.

ok, then i need to check the settings next. if i don't manage it, i will deactivate the blocker from now on everytime when i visit MG.
i think i could live with that^^

The blocker can block all the ads, just make sure it does not block that script:
/js/modulargrid.min.js

this script is not in the filter list and i do not know how to add it to the white list. there's still the option to pause addblock permanently for modulargrid, that is what i'll do.
thanks for your response anyway!

I got the weird problem that sometimes (like just a few minutes ago) almost all of my modules disappear from the grid and i have to add them again.

The adblock problem should be fixed so this might be an other problem.
In general if you are missing modules try to just reload the page...
