blank thread pages

[cuphongle]

Hello,

All of a sudden all my threads are showing up as blank pages
I have not done any modifications or anything to the site recently.

As you can see, the topics and the forum are showing up but when I click on a thread, nothing is showing up except a blank page, please help and guide me, I've looked up the manual and it showed me all the steps to test it out and I've tried it all but nothing is working, thank you.

Here is a page from the manual about troubleshooting blank or 'white' pages: https://www.vbulletin.com/docs/html/blank_pages

I would start by checking your error_logs (if you don't know where they are, ask your host)

Ok, so i am redoing the steps on the Manuals, i clicked on "plugins" and i ran into this error

So what should I do next? thanks

Parse error: syntax error, unexpected T_STRING in /homepages/27/d313341930/htdocs/VD/admincp/plugin.php on line 508

You clicked on plugins? Not sure what you mean there. If you think the problem is a plugin, then disable your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);
