Answer 1

Steps to try:

• Check whether vqmod is installed by calling https://domain.com/vqmod/install in browser. If not installed, then please scroll up and read the steps.
• Verify file name and path, also confirm that the code in search tag exists in the file mentioned.
• Check folder permissions. Make sure that vqmod/vqcache and vqmod/logs have 755 or 777 permission. If nothing works, then try 777 permission recursively for vqmod folder.
• Check the error logs in vqmod/logs.
• Check the installed vqmod version and the vqmod version given in xml file (), both need to be the same.
• Delete the files in vqmod/vqcache and check again. Also see whether vqmod copy of your file is generated or not.
• Move any vqmod xml file outside the vqmod folder and check. If everything works, move the xml back to the vqmod folder. I don’t know the reason, but it worked for me in some cases :) !
• – put this line at the top of the XML to make it valid and more compatible.
• Try the VQMod Manager extension. It may help you!

Answer 2

Really late answer but might help someone else in future: A > is missing at the end:

<input type="text" name="selection" value="<?php echo $selection; ?>" 
  id="selection"? 

should be

<input type="text" name="selection" value="<?php echo $selection; ?>" 
  id="selection"? >
