Hi!

Actually the plugin code instructs to only cache for an hour. Can you check your templates_c directory? It should contain a "serendipity_plugin_heavyrotation.txt" file, check its last modiufication time?

Regards,
Garvin

user@server1:/html/blog/templates_c$ ls -la serendipity_plugin_heavyrotation.txt
-rw-r--r-- 1 user user 72 2009-04-15 12:28 serendipity_plugin_heavyrotation.txt

When I delete the file (or create an empty new one), the sidebar doesn't display at all. I have tried reinstalling the plugin, but that doesn't help (nor does it create a new cache file for it).

Hi!

If the sidebar does not display, this would mean a fatal PHP error. HAve you looked inside the PHP error log and/or the HTML sourcecode to check for PHP errors?

To me it sounds as if the file cannot be written anymore, maybe due to permissions or a change in the server setup.

Regards
Garvin

I've played around with various permissions, but it doesn't help. Other cached content can be written fine. If i create the file with a simple "touch", the error message stays the same. If I edit the file and put *anything* in it, the sidebar displays (no php errors). If I then change the file date to some older date, I get the following error:

Hi!

Sadly I don't know much of the plugin. Currently it seems like it cannot recreate the .txt file as long as your "uploads" directory was recently modified; this is where the images for heavrotation are saved, and the code checks this as well.

If you edit the plugin.inc.php file and change:

Code: Select all

               if (file_exists($handler->getPath()) or file_exists($handler->getImagePath())) {


to:

Code: Select all

               if (file_exists($handler->getPath())) {


then the plugin should hopefully properly recreate the .txt file, and also update it accordingly.

HTH,
Garvin

Thanks for trying to help, but that doesn't change anything It's not that important, I can live without the plugin...

[garvinhicking]

Hi!

Hm, I'm really sorry for this. On my installation it basically works, so I'm not sure which could be the exact reason here. I could offer to have a look at your installation, if you can/want to provide me with FTP access to the site. Contact me via PM, if you'd like to try that.

Best regards,
Garvin

thanks for trying to help. again, it's not refreshing since you reinstalled it on my blog.
also, avatars seem to be broken. because they're also cached, this might be the same cause?

[mo]

i'd be grateful for help, i still experience the same problem, the cache file doesn't seem to get updated:

Code: Select all

web@server:/html/blog/templates_c$ ls -la serendipity_plugin_heavyrotation.txt
-rw-r--r-- 1 web web 50 2009-08-17 19:39 serendipity_plugin_heavyrotation.txt

drwxrwxrwx  4 web web   4096 2010-01-31 06:07 templates_c
drwxrwxrwx 19 web web   4096 2010-01-31 05:08 uploads

Hi!

It's hard to say without access to the server.... the permissions look okay if your PHP user is 'web'.

Regards,
Garvin

[lama]

when i look at this:

Code: Select all

-rw-r--r-- 1 user user 72 2009-04-15 12:28 serendipity_plugin_heavyrotation.txt

and this:

Code: Select all

drwxrwxrwx  4 web web   4096 2010-01-31 06:07 templates_c
drwxrwxrwx 19 web web   4096 2010-01-31 05:08 uploads

i am getting an idea of the error

[add]
but if that doesnt help you, tell php to log errors perhaps will help.
in your php.ini change error_reporting:

Code: Select all

# cat /etc/php5/apache2/php.ini | grep error_reporting | grep -v ";"
error_reporting  =  E_ALL & ~E_NOTICE


in your .htaccess insert:

Code: Select all

php_value error_reporting 2047
php_value display_errors 0
php_value log_errors 1
php_value error_log /path/to/php.log

of course /path/to/php.log has to be writeable by your webserver, "user" or "web", whatever it is;-)

the user names are consistent within the respective posts, both times i have edited my real username. you are right, i should have used the same edited name to avoid confusion.

i don't get any php errors logged until i delete the .txt , then i get

if i manually edit the heavyrotation.txt and chance it to a different artist/album, i don't get any errors logged, but the picture isn't downloaded/displayed.
