@brainjured,
Okay – take a minute and read the error message and it tells you the problem.
‘No such file or directory’ and the first names file is buttonsnap.php which is being looked for in ‘/blog/wp-content/plugins/subscribe2.php_/include/’.
The error is telling you that this file is not there. It needs to be.
Depending on how you install your plugins the issue could well be that you are not reading and following the upload instructions of you are installing manually via FTP or the upload is incomplete due to a software glitch.
If you installed using the WordPress administration area then the files are somehow corrupted, use FTP software to delete them – if you sue the administration area you will loose all of your settings and subscriber data. Then re-install.
