                <field name="mylogo" label="logo" type="accessiblemedia" />                

I tried to find where is the Error but couldn't find one, it is tested in XAMPP and doesn't generate any Error.

I am assuming that the templatedetails.xml file does exist in your hosting directory.

If your local XAMPP is on a Windows machine then you probably have an upper vs lower case character issue which is pretty common when developing on Windows and installing on a Unix based hosting accounts. On Windows the lowercase and uppercase characters are treated as interchangeable however this is not the case when you get to your hosting environment where an 'A' is not treated the same as an 'a'.

Based on your description I would be looking at the case of the the template file name mentioned here.


The actual file names needs to be templatedetails.xml and not templateDetails.xml or Templatedetails.xml etc.

The same issue of upper/lowercase characters could be involved in the contents of your templatedetails.xml preventing it from loading correctly.

Turn on Debug and Error Reporting and you might receive more useful diagnostics that might be more specific as to what the issue is.
