What else I need to do to add extension.
I added it to config.extensions.php in system folder but it is not working.
I forgot to mention this extension has more than 3 symbols.
Extension that is *.wotreplay.
Where I have to change it to get it working?
thanks in advance
How to get an error message?
I made it, just exchanged line 143 in pfs.inc
$f_extension = mb_substr($u_name, $dotpos, 5);
$f_extension = mb_substr($u_name, $dotpos, 9);
for change number of characters after the dot and all working well.
