Can you check the System Logs and Error Logs in your Admin Panel if there is a more detailed error message?
P.s. It would be better if you submitted a ticket at the client area as well about this btw.
You should not drop them, if by drop you mean deleting them. Instead you can truncate them.
But it would be better to wait first till you get a reply at your ticket.
Indeed. Once you have created your app, go to the Developement Center of your app, click the Extension menu and under core create the extension for MemberSync.
What is your forum about if I may ask? Have a look at this blog by @Matt. It has excellent points/advice and it makes for a very interesting reading, for new and old admins alike.
P.s. Do not underestimate the word of mouth as well.
What was the last modification that you did to your forum before this happened? Can you try to disable your custom plugins/apps one at a time till you find the culprit?
You can install plugins through the Plugins section at your Admin Panel. Click the Install New Plugin button, select the plugin 's xml file and click the Install button. Hope it helps.
Can you please tell me what do you mean by "Shadow banning"?
But yes, it does. The posts and topics of globally ignored members will be seen only by themself and staff members or other groups with the appropriate permissions.
Have a look at the plugins that you have installed. There you can find the hook number in the class name. It will look something like this for example: abstract class hookxxx extends _HOOK_CLASS_ Where the xxx stans for the numeric value of that hook.
Hope it helps.
Well, this error is occurring because the upgrader is saving the empty string value, (''), to the column 'starter_id', which is an integer. You can have a look at the upgrader I guess, but this is something that it best tweaked by specialists imo.
When you edit a forum, under Forum Settings you have this option: Minimum content count to see forum.
But it looks to me like you want users to see the forum, but not post until they reach a certain content count. I have not seen any such plugin myself. Have you looked in the MP?
You can run a sql query as well, although I would not recommend it doing it that way. Anyways, here is the query if you still want to do it.
DELETE FROM `forums_posts` WHERE queued = -1;
If you want to exclude the first post of the topic, i.e. the topic itself, run this query instead:
DELETE FROM `forums_posts` WHERE queued = -1 AND new_topic = 0;
And do not forget to make a backup of the db first.
If you go to your Mod CP, on the left site under HIDDEN CONTENT select Posts. There you will see an overview list with all the moderated posts. Select all rows per page and you can delete them all by clicking the Trash can icon for delete. Hope it helps.
P.s. It would be best imo, that before you do that, to make first a backup of your database. Hope it helps.
