* We have a self-hosted internal wordpress installation running:
wordpress 6.2.2tablepress
2.1.4I’ve inherited the task of editing a reports page that has a single table
that links to pdf files on a local server.Everything is running well after updating
wordpress/tablepress/php versions. The current table has several link in a single cell.However, when I try to save a table that has
a high number of links in a cell it gives the error:**Attention: Unfortunately,
an error occurred. There was a problem with the server, HTTP response code 400(
Bad Request).**The table will save until i try to input too many of the link lines in a single cell.I have several questions
but this can’t be the proper way to make this table.Should each file link be
in its own cell?I can upload an export of the table in csv or html format if
it will help. It is quite messy.

* Hi,
* thanks for your post, and sorry for the trouble.
* My assumption here is that your server’s firewall or security software somehow
doesn’t like these links with the internal URLs. Presumably, it thinks that hacking
attempt is going on (e.g. that someone is trying to extract internal data, or
maybe it doesn’t like the number of `\\` combinations, thinking that this string
is the escaping of e.g. a SQL insertion attack).
* To find out more, I would therefore suggest to check the various server error
log files for more details. The server admin can then maybe relax that security
software so that it doesn’t erroneously trigger these errors.
* Regards,
Tobias

* Before updating WordPress/Tablepress/PHP the tables were saving properly.
I will
look through the logs for this machine for anything that may be blocking it.I
haven’t seen anything from the antivirus/firewall reports that would reference
it being blocked. Thanks,

* Hi,
* yes, please check those log files. It might be something in the interplays of
PHP here.
* Best wishes,
Tobias
