Yeah I did not really mean “nay” assistance but thanks to anyone thinking about it!
In case anyone else has the same problem in future, I have tracked the cause but not the full solution. When clicking on the “insert a photo album” icon, the latest album created will show by default and if this has been used before, on say a different page, and is to be used on this occasion, then the value for the album ID in the shortcode inserted on the page is “0” even if this album value does not exist, and hence the fatal error (I guess)
If it desired to use this default album at this time then it is necessary to have another album in the list, possibly even an empty “dummy”, click on this and then back to the default and then insert and the correct value of the album ID should be inserted.
It would be nice if the plug in author could look at it and see if the bug can be fixed and mark the topic resolved
Regards
Jim
