.htaccess - WordPress site 500 error - RewriteCond: bad flag delimiters -

i see lots of other threads same issue, nil seems working me, , .htaccess file isn't complicated looks these others are.

everything fine until day or ago when site won't load anymore. gives me 500 internal server error.

looking @ logs on server see next happening:

[mon oct 20 04:08:21.546473 2014] [core:alert] [pid 4758:tid 139696409585408] [client 72.135.98.207:56622] /home/account/public_html/dynamictabletennis.com/.htaccess: rewritecond: bad flag delimiters

the .htaccess file nil more original, basic version utilize on wp sites.

# begin wordpress <ifmodule mod_rewrite.c> rewriteengine on rewritebase / rewriterule ^index\.php$ - [l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /index.php [l] </ifmodule> # end wordpress

i've tried deleting file on server , uploading fresh version of it, that's not solving problem. i've searched through other threads issue, seem have stuff in htaccess file other plugins , what-not i'm not using , doesn't reflect i'm seeing.

any info on how troubleshoot , resolved appreciated. thanks!
