SMF 2.0.18 - Need Help -

[Painlesstom]

Recently I've had some members using iPhones having issues making their posts since anytime they use an apostrophe, it and everything after it is gone when they post. I see the error in the logs for every time anyone uses an apostrophe, but only those with iPhones have their text removed in post. I've uninstalled all the smiley mods in an effort to effect a change, but to no avail. Need some expert direction. Thanks.

PHP version?  Have you converted database to utf8?

[Painlesstom]

PHP 7.3.27 and I just converted to UTF-8 as a result of your inquiry. I'll let you know if it fixed it.

Are you sure you're on 2.0.18?  That line does not match 2.0.18 code.  It is using older syntax, incompatible with php 7.3. 

[Painlesstom]

Yes, no doubt about it. So maybe that code is a leftover artifact that needs to be deleted? 

[Painlesstom]

And FYI I get the same error as you probably expected to hear.

did you install 2.0.18 or upgrade to it?

What mods do you have installed?

[Painlesstom]

Upgraded to it, but the problem didn't start immediately after the upgrades. It was weeks later, and during a period where I hadn't added or changed anything. Initially I thought it was a glitch with his iPhone, but other iPhone users had the same problem. The error log shows the same error for anyone that uses that ' character, but only iPhone users have had the rest of their text deleted when they post.

These 3 mods seems to be from SMF 1.x.x , and all 3 features are default for 2.0. Maybe his problem comes because of this mods.

Thanks for the suggestions guys, but none of those things made any difference. I deleted the offending code in the subs-editor.php file and that solved the problem. Posts are coming through intact now. Marking as SOLVED.

Deleting code randomly is not a solution.  It just makes the actual problem more difficult to diagnose

Also, randomly deleting any code that handles any user input may actually end up leaving your whole forum vulnerable to attacks.
