Hi,
I ran into this same problem and figured out it was because of the setting “short_open_tag = Off” in the php.ini file.
I actually edited the picker.php file and replaced ALL OCCURANCES of the short tags with full tags and it works 100%
For example (this type of change needs to be made in quite a few places):
Change:
<span>Maximum acceptable request var length: <?= $optionarray_def['gallery3_maxlength']; ?></span><br />
to
<span>Maximum acceptable request var length: <?php= $optionarray_def['gallery3_maxlength']; ?></span><br />
