Hi @dankingsley , what fieldtypes (or tabs provided by addons) do you have in that entry?

[dankingsley]

I've got it happening on a couple of simple sites I've just upgraded to EE7 and it's happening across all channels and entries.

• I expect it might be Structure since that has tabs/fields etc and would explain the universal issue.
• Fields are just fairly standard - RTE, Files, Text

(marking as possibly related to #2349 )

What is the channel type for this entry as set in Structure settings? Also maybe you could make a screenshot of how Structure tab looks for this entry? I'm unable to replicate this so far

[dankingsley]

The channel is a Page type within Structure. Although I've also just tried saving a listing type entry too and it's happening there too - basically every entry where Structure is managing the channel. I've just tried creating a new channel not managed by Structure and oddly this error doesn't occur, but #2349 still does!

And I've attached a screenshot of what is in a Structure tab - the only thing I've potentially done differently is move the standard URL title field to the Structure tab as well - although I've just tried taking that back out and the error still occurs.

I can happily give you access to one of the sites where it's happening if needed, just PM me on Slack?

Yep that fixes it @bakin1999

FWIW I had a customer using DataGrab report the same thing, and I could replicate it myself.

Came across the same error concerning another line in ee/ExpressionEngine/Service/Formatter/Formats/Text.php after upgrading PHP to 8.1.0.

Error message

preg_split(): Passing null to parameter #3 ($limit) of type int is deprecated
ee/ExpressionEngine/Service/Formatter/Formats/Text.php, line 160

Severity: E_DEPRECATED

Line 160: $censored = preg_split('/[\n|\|]/', $censored, null, PREG_SPLIT_NO_EMPTY); should probably be changed to $censored = preg_split('/[\n|\|]/', $censored, 0, PREG_SPLIT_NO_EMPTY);

@Zignature Thanks for posting this, what version of EE are you running?

[Zignature]

I've just updated to 7.2.5 from 6.2.5 and I updated PHP from 7.4.29 to 8.1.0
