Hi forsband.nu,
What version of MySQL are you running on?
Try reinstalling the plugin. Deactivate / Delete / Install.
This problem seems to be very rare and as such we're not quite sure what causes it.
Failing that, can you connect to your WordPress database with phpMyAdmin and try to run the following query? This will create it manually:
CREATE TABLE `wrprs_forsbrand_nu_wponlinebackup_activity_log` (
`activity_id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`start` INT(10) UNSIGNED NOT NULL,
`end` INT(10) UNSIGNED NULL,
`comp` TINYINT(2) NOT NULL,
`type` TINYINT(1) NOT NULL,
`encrypted` TINYINT(1) NOT NULL,
`compressed` TINYINT(1) NOT NULL,
`errors` INT(10) UNSIGNED NOT NULL,
`warnings` INT(10) UNSIGNED NOT NULL,
`bsize` BIGINT(20) UNSIGNED NOT NULL,
`bcount` INT(10) UNSIGNED NOT NULL,
`rsize` BIGINT(20) UNSIGNED NOT NULL,
`rcount` INT(10) UNSIGNED NOT NULL,
PRIMARY KEY (`activity_id`),
KEY `start` (`start`),
KEY `end` (`end`)
);
Let me know if you have any issue.
Jason.
