Hey,

Just to give you the resolution that I use for the Profile Picture error with 2CO Pay input.


go to \oc-content\plugins\osclass_pay\index.php

replace this line

<input name="Submit" type="submit" id="uniform-blue" value="'.$button_text.'">
with

<button name="Submit" type="submit" id="uniform-blue" value="'.$button_text.'">Upload new Photo</button>
And that's It, now is working

@Carlos
I am not sure if some payment types strictly require to have input instead of button.
