Mamba, according to your recommendation to update to version XOOPS 2.5.11 Beta2 I did, and the problem is over.
Now I am going to update two more sites to this new version 2.5.11 and all the files in Spanish as well.
May God continue to blessing you.

Thank you Mamba for your quick answer.
I check the xoopsconfig.php file and is correct on 'debugLevel' => 2,

The PHP hosting version in radioredentor.cl is ea-php74
Current PHP version Native (8.1) current see the image bellow



/**#@+
* Debug level for XOOPS
*
* Note: temporary solution only. Will be re-designed in XOOPS 3.0
*
* <ul>Displaying debug information to different level(s) of users:
* <li> 0 - To all users</li>
* <li> 1 - To members</li>
* <li> 2 - To admins only</li>
* </ul>
*/
'debugLevel' => 2,
