Sources/Load.php (Line 1592): Json decode error: Syntax error, malformed JSON

[m4z]

I'm seeing an issue similar to this 2017 thread about upgrade problems:

Code Select Expand

index.php?topic=555369.msg3936643#msg3936643 ("Sorry, you are not allowed to post external links."). However, in my case I'm in a fresh SMF2.1rc2 install.

Full error log entry:

• Type of error: Critical
• Json decode error: Syntax error, malformed JSON
• hXXps://redacted/~beta-smf/index.php?action=pm
• /home/beta-smf/public_html/Sources/Load.php (Line 1592)

The error appears often, probably for every request.

I have used the

Code Select Expand

SMF_UTF8_Diag.php script from the above thread and will try to attach the (redacted, no special characters removed) output.

I forgot to mention the env details:

• Debian 8
• Lighttpd 1.4.35
• PHP 5.6
• Postgresql 9.4

Ther is an error in the pg setup,
this get fixed by this pr: https://github.com/SimpleMachines/SMF2.1/pull/5593/files

You can choose to reinstall your version fix this fix or
to generated a new version of displayfields.

To generate the value new you can add a new custom fields under "Custom Profile Fields" and than remove it again.

Thanks, can you elaborate on the second case? I'd prefer not reinstalling (because I don't know yet how to save and restore the DB in that case). Where do I find these "Custom Profile Fields"? Are you refering to the SMF Mod of the same name? Can I add _any_ new custom field or does it have to have certain options?

[m4z]

Hmm, the mod isn't compatible with 2.1rc2 and gave an unspecified error during the first step of install, so I didn't proceed installing it.

[Arantor]

No, the mod was later built into SMF.

You need to go to admin, use the built in feature to add any new field, doesn't matter what, and remove it again.

[m4z]

After reading the SMF2.0 features and options docs and "How to use Advanced Profile Fields" in the wiki, I think you're referring to Administration Center -> Configuration -> Features and Options -> Profile Fields.

[Arantor]

Yes, that's what we're referring to.

[m4z]

Thanks, that fixed my problem mentioned above! (The offset errors from my other thread remain, though.)
