Thread:Project:Support desk/Uncomitted DB writes (transaction from DatabaseBase::query (LCStoreDB::get))

I have successfully installed mediawiki 1.23.6 on my laptop. I have imported a backed up version of a mediawiki site developed using mediawiki 1.23.2. When I restored the backed up version I successfully imported the database and copied the ZIP file of the whole directory that I had saved from the original mediwiki site created in 1.23.2. Everything seems to work fine except for the opening login page which gives this notice:

Uncomitted DB writes (transaction from DatabaseBase::query (LCStoreDB::get)). in C:\xampp\htdocs\mediawiki-test\includes\db\Database.php on line 4147

Any solutions? Thanks.
