I'll try to explain my way, if it's confusing you can just ask, I'm not really good at explaining. But anyways, first thing you'll need to do is to go to the multiplayer server list and click once the server
then, click 'edit' on the on the right bottom corner
there, you'll need to click the resourcepack off
then you'll need to join the server, and relog. After that you'll go back to the edit and put the resourcepack back on again
then just join the server and it should be all fine.
I won't say it will work 100% perfectly, but it has worked pretty well for me at least.
Edit: Oh wow the pictures won't work... well... hopefully you understand what I said..
