Description and Message
I have recently updated this forum from 3.0.8 to 3.0.10 with fresh phpbb files (without mods). Then I uploaded the root files and the file edits for board3 1.0.6, and I refreshed my style and emptied the buffer. Everything seemed fine except /portal.php shows a white page. I have tried reinstalling the mod, but I still get this white page. I hope anybody can help me out as to how I can fix this! Thanks!

Try to re-upload all of Board3 Portal's files again.

I had done that two times already without succes. Also tried to replace the original files one by one to find out which one gave a problem, but that didn't do much either. I did find the problem though, my provider uses php4 standard, and to use the forum with php5 I have to add a handler to .htacces. While updating to 3.0.10 I completely forgot to add that handler and once added the problem was fixed. Thank you for your support!
