My b2evolution Version: 2.x

<sigh> I have had an incredibly annoying day, problems with Google indexing and what not due to not having an appropriate redirect setup on my page. I finally found a solution (with the help of the Google webmasters forum) that seems to have fixed the discrepancy (or at least my queries are returning in the top 100 again), but now I have another problem, the preview function output in B2E is being redirected to the canonical address instead of displaying a preview. I'm not a programmer, but I'm sure it's because of the changed contents of my .htaccess file redirecting EVERYTHING. Please see the code below and to see if I can make changes such that the preview functionality will be restored - any help would be greatly appreciated!
