 * 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 />`
