I saw a post similar to this, but it was 7mos 2wks old, and updates were turned off. Also did not see a solution to the issue.
I am running Joomla 1.5.8 (and 1.5.9).
I have Legacy Mode Enabled,
And have metaWebLog .09 with RSD 1.3 installed (tested and funcional with Windows Live Writer)
I installed JComment 3.26, went through the configurations.
Was able to see the "Write Comment" link
Click on the link and launch the editor. Not sure if JComment uses its own built in editor,
but in Joomla, I use JCE 1.52.
Add my comments, fill in the Captcha data, and Click Send.
Once I click Send, I a popup window (in IE7, Firefox 3.x, and Opera) and 3 different web sites.
The popup error is "Request Failed"
I click OK on that popup, and following happens
The edit box fills with the following information
<b>Fatal error</b>: Call to undefined method JDocumentRAW::addHeadLink() in <b>/home/integr89/public_html/jtest/plugins/system/rsd.php</b> on line <b>76</b><br />
here is the code it is failing on ( line 76 is the line starting with $document-> )
I sure hope you are subsribed to E-Mail updates here! We have started discussing this very same RSD bug that is still around, and may get into fixing it soon since it appears to be abandoned but we are waiting for the creator to reply. Anywho, check out the thread over at
