Forum down after restart

phenomlab

Hi. I've restarted by NodeBB instance, and am now being met with the below error when trying to build (I can't even start)

Anyone seen this before ? This appears to be after a recent update to nodebb-theme-persona

@PitaJ Sorry I'm a little late responding here. I've used systemd as defined below, which works fine, and survives a rebuilt and restart

Many thanks for all the help and support. Greatly appreciated.

I also cannot remove plugins - similar error

Ran an npm cache clean and am now able to uninstall plugins (have temporarily removed nodebb-plugin-question-and-answer but now have this error on startup

Sounds like you are exceeding some limit on your system. Could be disk or memory. Is this shared hosting?

phenomlab

@baris No, it's my own VPS, but uses Webmin so I think you're right on the nail with quotas. Going to increase it now.

<baris>

./nodebb build writes a lot of files especially language files so there is quite a bit of IO going on.

phenomlab

@baris I've removed the quotas, and rebuilt, but still the same error on startup

PitaJ

Try ./nodebb build --series. Also try chowning the files to make sure permissions aren't the issue.

Oh was the build successful this time?

phenomlab

@pitaj said in Forum down after restart:

Yes, it was. No issues with the build, but unable to start NodeBB because of the error I mentioned above.

phenomlab

@PitaJ this is the error message

sudonix@vps:~/nodebb$ ./nodebb log

Hit Ctrl-C to exit


   61 |   <div widget-area="contentbetween"><!-- BEGIN widgets.contentbetween -->{widgets.contentbetween.html}<!-- END widgets.contentbetween --></div>
      |                                                ^^^^^^^^^^^^^^^^^^^^^^ `widgets.contentbetween` could refer to the top-level value `widgets.contentbetween` or the `.widgets.contentbetween` property of the current element, so compiler must emit code for both cases
      | note: Migrate to modern syntax to avoid the ambiguity. This will become an error in the future.

Unable to start no matter what I try. @baris @PitaJ any suggestions please ? This is a production forum.

Thanks

<baris>

Did you check memory usage? Make sure you have enough free memory and setup swap.

phenomlab

@baris That's not the issue. I have 16gb RAM with 4 cpu cores. I also have another forum called https://hostrisk.com running on the same box with no issues.

PitaJ

Try deleting node_modules and running npm i to reinstall. Try disabling all plugins. Try rebooting your server.

phenomlab

@pitaj tried all of this. Exact same error. Pretty frustrated right now by this - still not working.

phenomlab

All plugins are disabled, so it's not that.

PitaJ

Try downgrading persona to 11.2.6

phenomlab

@pitaj Same issue. Installed with npm i [email protected] but no difference. Error still persists.

PitaJ

Can you capture the output of ./nodebb dev just so we have a full log of the startup sequence?
