'Zend_Http_Client_Exception' with message 'Passed adapter is not a HTTP connection adapter
===

This is making my crazy. I really hate to post questions but "here goes".

I was able to upload a video using the Zend Gdata API for You Tube. "One video"...

Ever since I have received this error:

    
    Fatal error: Uncaught exception 'Zend_Http_Client_Exception' with message 'Passed adapter is not a HTTP connection adapter' in ../pathtoapp/Zend/Http/Client.php:926 Stack trace: #0 ../pathtoapp/Zend/library/Zend/Gdata/HttpClient.php(275): Zend_Http_Client->setAdapter(Object(__PHP_Incomplete_Class)) #1 ../pathtoapp/Zend/library/Zend/Gdata/App.php(692): Zend_Gdata_HttpClient->setAdapter(Object(__PHP_Incomplete_Class)) #2 ../pathtoapp/Zend/library/Zend/Gdata.php(219): Zend_Gdata_App->performHttpRequest('POST', 'http://uploads....', Array, Object(Zend_Gdata_MediaMimeStream), 'multipart/relat...', NULL) #3 ../pathtoapp/Zend/library/Zend/Gdata/App.php(910): Zend_Gdata->performHttpRequest('POST', 'http://uploads....', Array, Object(Zend_Gdata_MediaMimeStream), 'multipart/relat...') #4 /home/spotya/public_html/devblogpost/php/Zend/library/Zend/Gdata/App.php(985): Zend_Gdata_App-> in ../pathtoapp/Zend/library/Zend/Http/Client.php on line 926

Similar posts I found have solved the issue, but their solutions have not worked for me.
