Errors when deleting logs

I just moved my site to a new host. I uninstalled vbSEO sitemap and installed again. My old logs are still there, but when I go to delete them, I get the following error message:
Warning: fopen(/home/cmeinck/public_html/forum/vbseo_sitemap/data/downloads.dat): failed to open stream: Permission denied in /vbseo_sitemap/index.php on line 222

Warning: fwrite(): supplied argument is not a valid stream resource in /vbseo_sitemap/index.php on line 223

Warning: fclose(): supplied argument is not a valid stream resource in /vbseo_sitemap/index.php on line 224


Any suggestions?

It could be a permissions error from when the files were created. Try logging into your server as root and delete them that way. (Or ask your host to remove them for you.)

Can I login via FTP and delete them? Which files do I delete?

Thanks.

You should have enough permissions to remove them (which isusually root user if you cannot do it with your normal ftp user).

Which files do I delete?

All files in vbseo_sitemap/data/ folder.

Thanks Oleg. That did the trick.

Great!
