When top page navigation is enabled in instance-config.php the button form inside the page navigation bar is selected instead of the main post form with the correct action tribute causing the script to post to the action of the next button in the top page navigation bar instead of the action attribute of the form with the name "post" which caused the message "an unknown error occured".
A lot of bans can be removed from a tinyboard database because it isn't limited A staff member could select 100 users all at once with a simple javascript function and unban them all this needs to be limited because a staff member on an image board if they feel hostile they can just remove all bans on the tinyboard site easily without being limited to how many people they can unban at a time, this adds an option to limit it.
check if viewing a thread or viewing a board page when updating a thread so new posts do not appear at bottom of page while viewing threads list not sure if this was because of an outdated template but I thought I should point out this as it may affect html templates no matter the code as the banner code is the only code that checks where the user currently is.
