Default Corrupted whatsapp history

Hello everyone, i've been getting an error message lately on whatsapp about my history being corrupted.
First of all, I have a Samsung Galaxy SL i9003 rooted and flashed with cyanogenmod 11 4.4.2.
When i was receiving these corrupted messages all i had to do was click yes and it would restore them and take me to whatsapp again but this morning however when i'm clicking on yes, it shows me that it is restoring but i get the pop up that whatsapp has stopped & i can't open it.
I've tried restoring like 4 or 5 times but still i get the same pop up that Whatsapp has unexpectedly closed. I really need my messages that's why i am trying to restore them.
Do you think it is the cyanogenmod that's causing this?
I am uploading a screenshot of the error and another one of my ''About Phone'' stats.
Please help me guys!!
Thank you.
