cannot log in to SOME websites

[mapx]

are you using adblock plus or adblock.ini ?

which submit button ? where ? load some image

[mapx]

so, you disabled ABP for that site ? ==> it's not a solution, you can report in ABP forum
https://adblockplus.org/forum/

or in easylist forum
http://forums.lanik.us/

and someone will find the correct filter
