Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

Why ? changed the installation package, php 7.4, turned off the SGI, renamed xtt access, anyway, in theory it should be put with a bang from the "box"

Answer 1

Try to apply the fix described in this article from the official documentation:

ALTER TABLE `#__extensions` ADD COLUMN `custom_data` text NOT NULL;
ALTER TABLE `#__template_styles` ADD COLUMN `inheritable` tinyint(1) NOT NULL DEFAULT 0;
ALTER TABLE `#__template_styles` ADD COLUMN `parent` varchar(50) DEFAULT '';

Answer 2

We can’t guess here, write the normal text of the error.
