We are PRO users and have paid for several years out for support. We have had a ticket in for 3 days (live chat is not live, just leave a message) and have received no response at all. We upgraded to the newest version of the plugin. The search now returns zero results and there is an error message: Important warning: There are currently 1 entries in the search index that do not meet the indexing rules. You should run a partial index upgrade on these entries to resolve this warning. We tried upgrading, but the upgrade stuck at 0.28% for 2 days. This morning I paused the upgrade and instead selected to rebuild the index. Now we are stuck at 37.7%.
