Bug Blank Pages in Admin & No Queries Saved

[Tom]

I just upgraded from lite to pro and the following admin pages are blank with no error:

http://www.fordrangerforum.com/adminpp/vboptimise.php?do=resources
http://www.fordrangerforum.com/adminpp/vboptimise.php?do=test
http://www.fordrangerforum.com/adminpp/vboptimise.php?do=flush

I've added ini_set('display_errors', true); to my config.php file and there are no errors displayed, the page remains blank.

Also, the homepage statistics show:
MySQL Queries vB Optimise has saved this forum: 0

Help?

Without any error messages then there's nothing I can do even if I were to visit your site

Please contact your hosting provider for assistance with enabling error display.

Thank you for the quick reply. I forgot I had renamed my admin folder, and thus the blank pages in the admin section.

When I do a system test I receive this error/warning:
Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.

I'm using memcache. Please advise.

You may want to look into why your server displays a blank page instead of a normal 404 page

Please use the script found in the thread 6 threads down from this: http://www.dragonbyte-tech.com/f42/memcache-5508/index2.html#post32500 to test whether Memcache is working correctly.


For the future, could you please start separate support threads for separate issues? Thanks

Will do.

Please use the script found in the thread 6 threads down from this: http://www.dragonbyte-tech.com/f42/memcache-5508/index2.html#post32500 to test whether Memcache is working correctly.

Output is:
Server's version: 1.4.5
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
object(stdClass)#3 (2) { ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }

In that case it looks like the problem is that Memcache can't hold on to the data across page loads.

Try these 2 scripts on separate pages:

 <?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$tmp_object = new stdClass;
$tmp_object->str_attr = 'test2';
$tmp_object->int_attr = 456;

$memcache->set('key2', $tmp_object, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";
?>

 <?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$get_result = $memcache->get('key2');
echo "Data from the cache:<br/>\n";

var_dump($get_result);
?>

And see if you get the same result set when accessing the 2nd script within the 10 second limit.
