Same problem here. Twentyfifteen basic theme with almost no plugins active. medium multisite installation, installed and activated plug-in, can’t get in tablepress “You do not have sufficient permissions”. tried User Role Editor and turned on:
edit_others_tablepress_tables
edit_tablepress_tables
publish_tablepress_tables
read_private_tablepress_tables
tablepress_access_about_screen
tablepress_access_options_screen
tablepress_add_tables
tablepress_copy_tables
tablepress_delete_tables
tablepress_edit_options
tablepress_edit_tables
tablepress_export_tables
tablepress_import_tables
tablepress_import_tables_wptr
tablepress_list_tables
for administrators and I am superadmin of network.
Still can’t get into table press…

I still haven’t found out if it is plugin that is causing this. Sadly my misbehaving sub site is not the first subsite in the multisite install. I cannot for the life of me find what is special with this particular site…

Definitely mapping problem. As soon as I reverted back to 0.5.4.3 version the mapping works. I will try to find out what is singular for this particular site compared to the other domain mapped sites that work fine in 0.5.5 ver on this MS install. It is not a unique plugin or theme so probably a combination of plugs or theme plug interaction.

Verified the 4.0.2 release and now everything works brilliant. Sales/ticket delivery/online and offline Validation, it all just works.
Thanks a lot Malcolm for your efforts. Super support and response.
Cheers!

Added information: I have tried to export logged in as both network administrator and as site administrator.
The only network-wide plugins activated are:
domain mapping
supercache
wordfence
anti splog
comment indexer
google indexer
installer
multisite privacy
multisite plugin manager
snapshot
user reports
wordpress network theme stats

the multisite handles more than 50 sites.
All data from the tickets are in the database and the OFX export works OK
Investigating further and I will try to find if there is a plugin conflict.

Im also interested in getting this plugin a bit more up to date. I really like its clean interface and nice functions.

I have a similar problem:
I have recently changed the url of my blog (self hosted)from server02.domain.ext to https://www.domain.ext. I was using the first name for testing purposes and when I finally deleted the old www site and changed the dns to point to new one (server02) everything workes fine. I changed the correct options in WP and the new https://www.domain.ext works perfectly. In my statistics page it tells me (correctly, I might add) that I now have two sites (server02 and www). How can I merge the statistics for two sites into one, or if that it not possible, how can I delete all statistics and the site entry for server02 ?
It just bugs me a bit to have an old and useless statistics up on my dashboard.
