Hi,
the form submission takes quite long time when some images are attached to a post.
I don't think this is due to this plugin but maybe you have a trick.
Do you know why it can take quite some time?
Could it be the image processing in wordpress? I notice it generate 12 images sizes for each image submission.
3 defaults, 5 from the SELA theme, and I don't know where the 4 others are generated from.
You can try to deactivate all plugins except MB plugins and switch to the default theme of WordPress (Twenty Twenty) to submit the form again. Then activate plugins one by one and switch to the current theme (SELA), this way could help you know where the problem comes from.
