Your database user has limited access

Hi @cr0co!

The important part of that message is this:
“Your database user has limited access and isn’t able to run DROP or ALTER database commands. Contact your server host and ask them to fix this for you!”

So you should ask your server host to make your database user have permission to do DROP and ALTER database commands. This documentation can explain this further if needed:
https://smartslider.helpscoutdocs.com/article/1994-database-issues#duplicate

This is the file, that causes your problem:
\wp-content\plugins\smart-slider-3\Nextend\SmartSlider3\Install\Tables.php
from line 95.:

$hasIndex = Database::queryRow(Database::parsePrefix("SHOW INDEXES FROM '#__nextend2_section_storage' WHERE Key_name = 'application'"));
if ($hasIndex) {
	$this->query("ALTER TABLE '#__nextend2_section_storage' DROP INDEX 'application'");
}

...

$this->query("ALTER TABLE '#__nextend2_section_storage' ADD INDEX 'application' ('application', 'section'(50), 'referencekey'(50))");

The logic behind the code is, that the $hasIndex checks whether or not application index exists.

At the next line, if this index exists, it gets dropped.

The last line creates the same index again, and this is where your error happens.

There are two possible cases:
1. This line doesn’t works:
SHOW INDEXES FROM '#__nextend2_section_storage' WHERE Key_name = 'application'
where we are checking the existence of the application index.

2. This line doesn’t works:
ALTER TABLE '#__nextend2_section_storage' DROP INDEX 'application'
where the application index would be deleted.

You should ask your server host why one of these wouldn’t work in your case. I suggest showing them our file, where they could debug which one, if they still doesn’t seem to figure out the error within their configuration. But at all our users where this issue happened before, 2. was the problem, due to wrong user permissions.
