Hello guys,
I try to install Link-tools-1.3.2 plugin but, I give this error:
MyBB has experienced an internal SQL error and cannot continue.
SQL Error:
1101 - BLOB, TEXT, GEOMETRY or JSON column 'preview_data' can't have a default value
Query:
CREATE TABLE mybb_url_previews ( url_term varchar(2083) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL, preview_data text NOT NULL DEFAULT '', dateline int(10) unsigned NOT NULL DEFAULT 0, valid tinyint(1) NOT NULL DEFAULT 1, previewer_class_name varchar(100) NOT NULL DEFAULT '', previewer_class_vers varchar(15) NOT NULL DEFAULT '', KEY url_term (url_term(166)) ) CHARACTER SET utf8 COLLATE utf8_general_ci;

I removed 'sid' => NULL line, but problem still persist.
Anyone can help me?
PS: Mybb 18.x
Thanks
Hi there. Plugin author here. Sorry about this. This error is probably due to STRICT_TRANS_TABLES being included in your database's sql_mode setting. The plugin ought to avoid this error though in any case, so it's not your fault.
I think that the plugin should probably work OK even with that DEFAULT '' after preview_data text NOT NULL being removed (in inc/plugins/linktools.php in the lkt_install_or_upgrade function). If you would be willing to remove that and test whether the plugin works OK, I would really appreciate it. If you are successful, then I can include that fix in the next release. Otherwise, we can try alternative approaches.
Thanks for your bug report!
I removed line 292 from but error still persist:

Laird said to remove DEFAULT '' from the line, not all the line.
preview_data text NOT NULL DEFAULT \'\',
change with
preview_data,
Probably better instead would be to change to:
preview_data text NULL,
Briefly tested on a local installation and seems to work OK. Let me know how you go though. And thanks Crazycat for your succinct intervention - more succinct than I would have been!

That's not surprising given that according to the code you pasted, you haven't changed the relevant line at all. It is still as it was originally.
To be very clear, you need to change line 292 of
inc/plugins/linktools.php from:
preview_data text NOT NULL DEFAULT \'\',
to:
preview_data text NULL,

Try uninstalling and then reinstalling the plugin.
