@iwan155 – The reference to wp_footer() is not relevant with the Atahualpa theme.
Have you looked at possible active plugin conflicts? You might also just need to clear your image cache under Gallery > Other Options > Miscellaneous and/or need to use the Reset Option under Gallery > Other Options.
Thanks!

Emptying the cache didn’t help. I do run some plugins, but switching them off is not an option… I tried a few but that didn’t help either.
@iwan155 – Standard troubleshooting would be to deactivate *all* plugins then reactivate them one at a time. Granted this can be cumbersome and inconvenient but it generally does not take very long to do.
