The upgrade went well until the last few steps where the forum language wouldn't compile.
To remedy this I had to change file permissions in:
/var/www/public_html/modules/boonex/forum/classes/en
/var/www/public_html/modules/boonex/forum/js/en
/var/www/public_html/modules/boonex/forum/layout
/var/www/public_html/modules/boonex/forum/layout/uni_en
FROM 644 to 666
I believe from a recent security course I took that files at 666 are potential security risks.
Not sure how to proceed? Whether to change the files back to 644 now the upgrade was done ok and language files now compiled successfully.
Any comments appreciated. Thanks.
