Plugin Install Errors

[siringo]

Hi,
I receive errors like the following when I try to install a plugin ....

Trying to open URL package_event_en.xml...
Fetched 131072 bytes from the URL above. Saving file as /home/what4x4/public_html/blog/templates_c/package_event_en.xml...
Cannot write to file /home/what4x4/public_html/blog/templates_c/package_event_en.xml.

This error can happen if a plugin was not properly downloaded (check your plugins directory if the requested plugin was downloaded) or the inclusion of a file failed (permissions?)

Fatal error: Call to a member function introspect() on a non-object in /home/what4x4/public_html/blog/include/admin/plugins.inc.php on line 441


Any ideas?

Many thanks,

I receive the same error messages. Some pugin installations worked, though.
/blog/plugins is "drwxr-xr-x 41 www-data www-data".

Hi siringo!

Cannot write to file /home/what4x4/public_html/blog/templates_c/package_event_en.xml.

You must ensure that this directory/file is writable for your PHP/webserver user.

Best regards,
Garvin

Thanks for the help Garvin. I've got some permissions problems, my host stuffed something up and my blog is all over the place.

Thanks again.
