error editing an item (impossible editing)

In some tables (either myisam or innodb) I get this error:

CODE: SELECT ALL
Warning in ./libraries/classes/InsertEdit.php#1765
 implode(): Invalid arguments passed

Backtrace

InsertEdit.php#1765: implode(

string 'pro_doct',

index.php#43: PhpMyAdmin\Routing::callControllerForRoute(

And in phpmyadmin I cannot copy tables from a (local) database to another (local) one, as I had always do. Now I can only export/import (without error messages).

I use xampp for Linux.

EDIT

I noticed that now I cannot create views anymore: the "create view" link doesn't work anymore.

EDIT

My question is: how can I use the console to check what kind of problem there is, and how fix it?

Learn to use the "mysql" CLI.

To copy data from one table to another (assuming compatible schema definitions):

INSERT INTO db2.t2  SELECT * FROM db1.t1;

VIEWs have been around for a long time. What version of MySQL are you using?

CREATE VIEW foo(a INT, b VARCHAR(22))
AS SELECT ...;

(There are other options; see https://dev.mysql.com/doc/refman/8.0/en/create-view.html .)

Caution: MySQL Views are syntactic sugar; do not expect any performance benefit.
