Those strange characters such as shown in 'GPSVersion = ' show as a blank within Piwigo.

Firefox Fxif reads the Metadata OK as here for that image:

Could it be viewing direction that is leading to the problem?


The image this relates to is here:

The line 205 error message is suppressed as the line is rem'd out.

I have attached the image jpeg file to this post.

Thanks again.
