Topic: [SOLVED] Cache directory not writeable in standalone mode

[kai920]

I'm using SP 2.2.2 with SMF 2.0 RC1.2.

SMF is installed in /forums, and I copied the standalone php file to /index.php and changed the $forum_dir variable. The portal homepage loads fine on /index.php but I'm getting this warning:

The cache directory is not writable - this will adversely affect the performance of your forum.

I've tried changing the /forums/cache directory to 777 or 775, 755 but the message persists. Note that it only appears on the portal's standalone index.php file and not anywhere else.

If SP is in the default setting of Frontpage mode I do not see the performance warning on the portal page (/forums).

Any ideas?

Question is it solved or did this error appear?

[kai920]

Not solved.

I need some ideas on how to eliminate SP as a potential cause for this...

Well, I haven't seen this before really. Try adding this after SSI.php is included in standalone file:

var_dump($cachedir);

It will echo the relative path to cache directory. See if the path is correct.

[kai920]

I included var_dump($cachedir); and it says NULL when I load the frontpage (standalone file).

[kai920]

Any reason why $cachedir would be null? (I only see the warning on the standalone php page)

[???1031]

Did you disable the complete cache?
Possible this will not fill this value.

[kai920]

My cache was disabled, but I changed it to Level 1 and it still shows the warning - on the standalone php page.

(is the cache warning supposed to show on other pages?)

[???1031]

No i only ask if you disabled it =). Possible that the reason why the $cachedir is empty. I want only find a hint for the empty cachdir value and this would be a good reason.

[kai920]

Well as I said, I enabled caching (level 1) and the warning is still showing...

[kai920]

Still seeing this on SP 2.3. Not a showstopper by any means, but I'm just curious why the message is there...

[kai920]

Might be related to this.

Sorry for the long wait on this issue.

I have another suggestion, have a look in your 'Settings.php' file.

Is the $cachedir variable defined there? index.php will give $cachedir an automatic value in case your Settings.php file is corrupt, something that SSI.php doesn't. That would explain the issue with the Standalone mod for the portal.

[kai920]

Ah, you may be on to something

There's no $cachedir in settings.php. Should I just add it in?

[Nathaniel]

Yes, add it after the declaration of the $sourcedir setting. Make sure that it is the exact path to your cache directory.

[kai920]

Very nice, the message is gone now. Thank you 

shouldn't this have taken care of the message in the standalone php file?

Code: [Select]

// Make absolutely sure the cache directory is defined.
if ((empty($cachedir) || !file_exists($cachedir)) && file_exists($boarddir . '/cache'))
$cachedir = $boarddir . '/cache';

[Nathaniel]

Yes, it should have worked anyway. I can only replicate this issue with the Settings.php file, if I remove all references to $cachedir.

My Settings.php file on a SMF 2 RC1.2 test install that was installed with the full install package works has the code below:

Code: [Select]

if (!file_exists($cachedir) && file_exists($boarddir . '/cache'))
$cachedir = $boarddir . '/cache';
Your 'checking code' for the $cachedir may be from an older version of SMF, but it should still work...

I can't say I am sure why it wasn't working, I'm glad its working now though.

[kai920]

Tried your code, doesn't work either unless I have the specific $cachedir definition in settings.php. Strange..

Just experienced the same problem. I had just enabled Level 1 Cache in SMF 2.0 RC3 with SP 2.3.2.

Previously the cache was set to No Cache.

FTP and SMF reported that the directory was set to 777 but my standalone page reported this error.

Adding $cachedir to my Settings.php file and setting the full path removed the error message.

Thanks.
