Sorry if this is the wrong place for this – if so, please direct me to a more appropriate list/site.

My MediaWiki software (version 1.3.0beta2) has been buzzing along fine for a long time, but then suddenly a few days ago all pages started displaying this error:

//QUOTE

Warning: _loadcachedcode(/tmp/tpl_0_7_0_1ea1690d778636860620e7d464dd8938.php): failed to open stream: Permission denied in /home/allalias/public_html/guide/PHPTAL-NP-0.7.0/libs/PHPTAL/Template.php on line 430

I looked at the section it seems to be referring to, /PHPTAL-NP-0.7.0/libs/PHPTAL/Template.php lines 428-432:

//QUOTE

function _loadCachedCode()

{

include_once($this->_codeFile);

$this->_code = "#loaded";

}

//ENDQUOTE

Any ideas on what might be going wrong, how I can fix it, or where I should look to solve this problem?

Thanks in advance for any help, Charlie Sellew charlie.sellew@gmail.com
