There is an error in your first file tag code. Most probably:
- Wrong file location (
catalog/view/theme/shopitout/template/common/header.tpl
) . - Or mentioned search code doesn't exist in
catalog/view/theme/shopitout/template/common/header.tpl
Proof for the above statements:
- Move the second file tag to first - Working.
- Or remove the
error="abort"
parameter form first file tag - 2nd file code Working
if you still can't find the error, then refer the section under the heading - Opencart Vqmod xml file not working??
