Professional WordPress Plugins and Services. wpDiscuz, WooDiscuz, Advanced Post Pagination
Just purchased Advanced Attachments plugin and I'm having some problems. When trying to upload a video file to the forum I get the "Please upload a valid image" message. Am I doing something wrong? The video is only 60MB and I think I've set max file size to 256 MB.
This is not wpForo forum plugin. What is this? Where are you trying to use the addon? The wpForo Advanced Attachment addon is only for wpForo Forum plugin: https://wordpress.org/plugins/wpforo/
