We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
Still same error even changing to 20MB. Is there another setting somewhere that could also be set to 128Bytes?
Is you go to Wordpress dashboard / Media / Add New, what max size is reporting ?
Can you upload in there correctly ?
Please read this support topic and make sure you've set correct value for Max Uploaded File-size in Bytes in Advanced Attachments settings (Forums > Settings > Addons > Advanced Attachments). Also check the same option in Dashboard > Forums > Topics & Posts.
Also, the Max Uploaded Size should be equal with Max Post Size in PHP Settings, this should also be checked.
