How to migrate to SMWSQLStore3 without shell access?

I couldn't even get to step 4.

I transfered the new files (SMW 1.8) to my server and called the directory "SemanticMediaWiki_new". If I don't have the line $smwgDefaultStore = 'SMWSQLStore2'; and I rename the directory to "SemanticMediaWiki" (so that it becomes active) I immediately get the error message.

If I have the line $smwgDefaultStore = 'SMWSQLStore2'; it works and SMW 1.8 is shown in Special:Version (like it is now) - but as soon as I remove the line I get the error...

I am quite sure that you are not on Special:SMW-Admin when getting this error. What happens if you enter the URL to Special:SMW-Admin directly in the browser?

I'm pretty sure I tested this as well and received the same error message...

Is it maybe a problem if I have two directories with SMW in my extensions folder - one called "SemanticMediaWiki", the other one called "SemanticMediaWiki_old" ?

My fault - it seems I wasn't at Special:SMW-Admin when I received the errors in February.

Now I managed to update my database to SMWSQLStore3 :)
I ran the database update twice (as you suggested). Just for curiosity: Why does it need to run two times?

Ouch, I did not notice you post of Feb. 9, 2013 or forgot to answer O_o. Cool that it worked out for you. It would have been really really weird if you were on Special:SMW-Admin and receiving this error. I think that Markus posted to the mailing list on why the refresh has to be done twice. I cannot remember what it was, but it is definitely necessary since to my experience only about two thirds of the job is done in the first run.

Thanks for your reply.
I guess it's time to implement the Like button into LQT :)
