User profile problem
log error would help, it might be a redirect loop so try first to update your permalinks and save, even without any changes just press the save button.
Didn’t work again
a 104 MB log is weired you can try the following :
1 – if you need that log download it to your llocal machine, if not go to step 2
2 – delete that file
after deleting it, try to access the page where you had that error,
if the errors goes away i may sa that your server has issues trying to log more error on your BIG SIZE file
other wise you will get a more signifiant error that you can copy paste here so we can help.
post the 5 recent log from error, that will be enough. And enable permalink as jdev said, I check your site, permalink was disabled.
I followed all what you have said @jdev and @rahul but the problem is still unsolved.
Below is the recent error_log as Rahul suggested:
[01-Jul-2015 06:41:18 UTC] PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 39583744 bytes) in /home/princefaqx/public_html/flyanswers.com/wp-content/plugins/anspress-question-answer/includes/user.php on line 592
Thank you for all your time on this.
