hi all, we are also having a similar issue:
soap 1.1. magneto 220.127.116.11
We developed an app that pushes and retrieves data from one program to Magento via the Magento API via SOAP.
This is the kind of post would we send to the magento store:
[08/Oct/2013:16:49:59 -0400] "POST /index.php/api/soap/index/ HTTP/1.0" 200 266 "-" "-"
Basically when we attempt to send these commands to the Magneto site / Server
it stops and we receive the following error:
MAGENTO::ERROR: looks like we got no XML document"
During the connection, the actual return from their magento web service is as follows:
Warning: include() [function.include]: Failed opening '/home/sistaco5/public_html/includes/src/Jemoon_Htmlminify_Model_Observer.php' for inclusion (include_path='/home/sistaco5/public_html/includes/src:.:/usr/local/php53/pear') in /home/sistaco5/public_html/includes/src/Varien_Autoload.php on line 93
This does not look like an XML.
I believe the error may be related to BOM I found at the following article:
Not sure if this above article will work, but any other thoughts on how to address the above would be very much appreciated.
Look forward to your help and support guys / gals!
