I loaded the latest update and now my site has been down for 12 hours. I followed suggestions in other posts to delete the quick-cache folder from my plugin files and to delete the advanced-cache.php from my wp-content. However, I still get an error message: Parse error: syntax error, unexpected T_STRING in line 18 of my wp-config.php. I've checked it and it seems fine. At the moment, I'm hoping my host can restore my entire site from a backup but I'd love a quicker fix. Any more suggestions?
