Form submit = SQL Error

[GasmoN]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Install plugin as usual
2. Add new form (just one text object for testing purposes) and submit field
3. Type a text inside textarea you just added
4. Try to submit a form
5. https://prnt.sc/ulCPM8ySEo7O

Expected behavior
It should submit it normally

Desktop (please complete the following information):

• MyBB version: 1.8.38
• Plugin version: 2.6.6
• PHP version: 7.4.33
• MySQL version: 10.11.9-MariaDB

Please add an export of your form if the issue is within processing the form

[{"name":"test","active":"1","fid":"-1","tid":"0","overridebutton":"0","class":"","settings":{"allowedgidtype":"0","allowedgid":["4"],"customdenied":"","limitusage":"","pmusers":"","prefix":"0","uid":"","customsuccess":"","signature":"0","posticon":"0","showsummary":"0","summaryparsed":"0","customsummary":"","width":"","labelwidth":"","pmgroups":[""]},"subjecttemplate":null,"messagetemplate":null,"fields":[{"fieldid":"1","name":"TEXT","description":"","type":"2","default":"","required":"1","order":"0","class":"","settings":{"placeholder":"","maxlength":"","regex":"","regexerror":"","cols":"","rows":"","resize":"1"}},{"fieldid":"2","name":"Send","description":"","type":"11","default":"","required":"0","order":"1","class":"","settings":null}],"usage":[]}]

EDIT:
After checking error logs, this is what I found

SQL Error: 1364 - Field 'datetime' doesn't have a default value Query: INSERT INTO mybb_fc_formusage (formid,uid,ref) VALUES ('1',1,1)

To fix it, deactivate and uninstall plugin. Edit the following lines in class_formcreator.php and upload that edited file
array(
"Field" => "datetime",
"Type" => "timestamp",
"NULL" => 0)));

--->>

        array(
            "Field" => "datetime",
            "Type" => "timestamp",
            "NULL" => 1)));

then install and activate plugin.

And there is also issue if "post as user" is -1. It should post as bot but instead it gives this sql error.

SQL Error: 1264 - Out of range value for column 'uid' at row 1
Query:
INSERT
INTO mybb_threads (`fid`,`subject`,`prefix`,`icon`,`uid`,`username`,`dateline`,`lastpost`,`lastposter`,`lastposteruid`,`views`,`replies`,`visible`,`notes`)
VALUES ('17','Form submission: test',0,0,-1,'Form Creator Bot',1737029477,1737029477,'Form Creator Bot',-1,0,0,1,'')

Temp FIX: Just leave the option empty so the user who submitted a form will be also the author of it.
