hi
when i sign in my site it qives me a blank white page
and the same when i save plugins edit ,, any save button in admin cpanel, and when i sign out
when i refresh the page after the blank page it goes to the right page.
for example , it sign me out but the page doesnt refresh itself ???!!

i didnt upload any new plugin
but i edited the
/ow_system_plugins/base/controllers/join.php
and
/ow_system_plugins/base/views/controllers/join_index.html
in order to remove the standard capatcha , the i noticed the problem , i dont know if this cause the problem , so i go back with my edits but the problem still the same
