White pages randomly increasing

[NJ_Lowell]

Our Forums had been running without issue until yesterday morning. I checked and see no changes to our forum had been made and no changes to PHP or other software had been made.

I have reviewed - https://www.vbulletin.com/docs/html/blank_pages and do have PCRE Library Version 8.21 but like i said its been this way for awhile I can't see it all the sudden becoming an issue.

It started with not being able to edit posts and now you cannot view private messages and then last things to take place are now you cannot post a new thread or cannot access only 1 of our threads/forums. All of these issues show a white page.

So if I take http://www.mywebsite.com/support/for...splay.php?f=12 the one that is not working and gives only a white page and replace with one that does not exist i should get the below as tested on another site but still receive a white page.However all others seem to be working.

Message

Invalid Forum specified. If you followed a valid link, please notify the administrator

Anyone have any ideas? Also thanks in advance.

Update:

I am still experiencing the same issue but no new white pages or issues, however using developer tools I found the below as my edit users screen's template is not fully loading, User Edit screen providing a white screen around the user details.

Below is - vbulletin_date_picker.js

White Pages are indicators of PHP errors. You need to look at your PHP Error and HTTPD Error logs to see what the errors are. To be up to date with current versions of PHP, you need to upgrade your vBulletin. You can only use PHP 5.2.X on your version. To use PHP 5.3.X you need to upgrade to vBulletin 3.8.7. To use PHP 5.4.X, you need to upgrade to vBulletin 3.8.8 which is currently in Beta.

Hi Wayne,

We are currently using PHP 5.2.17. I have looked through the logs and do not see any errors with the exception to missing files, which in these cases are expected.

I am looking at purchasing support for a month to get this issues resolved, will this be supported and something easy for your team to locate and resolve?
