[Plugin: All in one SEO pack] 80 MB of error log in log files on server.

Hello
I’ve checked my log_files (I have a server with 5 websites running AIOSP) and it’s full of this error:

Sun Jun 20 16:02:24 2010] [error] [client 95.7XXBB.131] PHP Warning: error_log(/var/www/vhosts/website.some/httpdocs/wp-content/plugins/all-in-one-seo-pack/all_in_one_seo_pack.log) [function.error-log]: failed to open stream: Permission denied in /var/www/vhosts/website.some/httpdocs/wp-content/plugins/all-in-one-seo-pack/aioseop.class.php on line 986, referer: https://www.website.some/category/name

It’s scaring, as the log file is about 80Mb with same error.
Please, advise me about solutions, if any.

I’ve already posted the same before, but the title wasn’t correctly typed. Consider this topic.
