hi
Ok,
the ID speaks: 8388607
it is the max value for auto-increment, so it is not stored nothing in DB.
This is a limit of original statpress to have the key as incremental.
One alternative is to increase his size. The problem is that this will stop the update in almost all site that has some data, has the operation took many times and service provider block the request for sure (I test it in my sites, so that change in table definition where not apply in new-statpress to avoid blocks on sites).
Another alternative is to prune old data and set the id to start from 1 again.
As you have only one record, maybe you already have the prune activated?
To set again a low value the instruction to run into myphpadmis is:
ALTER TABLE wp_statpress AUTO_INCREMENT = 1;
You had to do this only if auto-prune ia activated otherwise there will be a collision from new data inserted and old data
