I just did the 5.21 to 5.30 upgrade. Everything looks normal and all of the thumbnails come up when looking at albums. However, if I try to click a thumbnail and view the full size image, I get this error:
Fatal error: Call to undefined function: construct_editor_styles_js() in /var/www/html/photopost/showphoto.php on line 934
I have verified that all the images are where they should be. I can link directly to the image by simply entering a link in my browser window, so I don't think there is a permissions error.
If there is any other info you need regarding any settings that might cause this, please let me know and get the info and double check all settings. Thanks!
Hopefully, this will be the last issue after the upgrade. Has been relatively straight forward so far.
