When i click on System Test i get the following error: Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.

Why is that?

Try creating these two scripts and run them in turn:

<?php apc_store('test', 'Working!', 10);

 <?php echo apc_fetch('test');

If the second script does not print "Working!" on the page, then there's something wrong with your APC configuration. Please contact your web host for assistance.

I get

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting T_STRING in /blabla/webseiten/test.php on line 9

with the second script i get a blank page on my site.

My configurations:

[APC]
extension = "apc.so"

apc.enabled = 1
apc.shm_size = 64M
apc.ttl = 0
apc.user_ttl = 0
apc.enable_cli = 1
apc.max_file_size = 10M
apc.stat = 1


but this works:

<?php
apc_store('test', 'Working!', 10);
echo apc_fetch('test');
?>

The script I posted is not 9 lines long, so the PHP error you described is impossible. Please create a new PHP file and put ONLY the line I mentioned in there

[Fillip H.]

That is wrong, you need to create two separate scripts as per my original instructions. Your script does not test whether APC can retain cache across pages.

 

[Majora]

With "apc_store" something is written into the cache and then "apc_fetch" read it right?!

 

[Fillip H.]

That's correct, but calling them in the same script (i.e. in the same request) does not accurately test the ability for it to retain the cache in memory.

 

[Majora]

With

<?php echo apc_fetch('test'); unter http://www.faq4mobiles.de/test.php

I get a white page.

and with <?php apc_store('test', 'Working!', 10); under http://www.faq4mobiles.de/test1.php i see a white page, too.


Why don't i need the "?>" to close the code?

 

[Fillip H.]

You need to run the script containing apc_store first as per my original instructions.

 

[Majora]

Yeah..but it doesn't work for me. Ich click on the second link and then on the first one after that...

 

[Fillip H.]

In that case, APC is not correctly configured on your server. Due to the vast differences in server configurations I'm sadly unable to assist you in fixing the server module, so you should contact your host

 

[Majora]

My configurations (http://www.dragonbyte-tech.com/f42/running-test-fetch-cache-failed-8175/#post46291)

What is wrong?

 

[Fillip H.]

I can't see anything wrong in your configuration, that's why I suggested you request help from your host. Show them the two test scripts you created.

Those test scripts are 100% independent from vB Optimise, so it clearly demonstrates that vBO is not at fault
