I see these messages popping up when I trigger a sync in the News android app. fyi @David-Development
This was also mentioned in the linked issue.

Still there after 21.0.2 upgrade... Really annoying as the log is flooded with hundreds of entries a day

cRUSHr2012 · 2021-05-26T20:38:47Z

Hi, I had this problem after updating between PHP 7.3 minor versions and also updating from Nextclod 19 to Nextcloud 20.
It seems the permissions for /var/opt/remi/php73/lib/php where changed to apache user instead of my nginx:nginx setup.
The outcome was that i could not login using the web interface.
A chown -R nginx:nginx /var/opt/remi/php73/lib/php solved it.

#25806 mentions this issue. Appears to be a compatibility issue with PHP 8.x.x

After downgrading to 7.4, no issues anymore. I would suggest if you can, downgrading to PHP 7.4 in the meantime.

yan12125 · 2021-06-23T04:17:45Z

This issue persists in Nextcloud 22.0.0 beta 5 on php 8.0.7.

kiv57 · 2021-07-05T10:18:23Z

Still there after 21.0.3 upgrade, PHP 8.0.8.

Edit : the above fix seems to do the job.
Is there any risk of "false negative", a regular error that would be hidden with this fix ?

sosed213 · 2021-07-09T02:43:00Z

I have this problem.
Nextcloud 22.0.0
PHP 8.0.8

yan12125 · 2021-07-09T02:50:13Z

Is there any risk of "false negative", a regular error that would be hidden with this fix ?

I don't think so. The fix #27631 hides errors that are suppressed by the error control operator (@). Those are intended to be hidden. I just make the behavior on PHP 8 match that on PHP 7.

apg1980 · 2021-07-14T05:41:45Z

Good morning, i got the Error: session_start(): Ignoring session_start() because a session is already active at /var/www/nextcloud/lib/private/Session/Internal.php#206 error in Nextcloud 22 as well (again).

yan12125 · 2021-07-14T05:50:29Z

Good afternoon :)

That's expected - the fix is in git master (Nextcloud 23) only. The same fixes for Nextcloud 21 and 22 are on the road - see [stable21] and [stable22] pull requests mentioned above.

ManySolutions · 2022-12-22T05:21:33Z

I am currently getting this issue, I don't see a esolution to this? I am using Nextcloud Hub 3 (25.0.2)

juliushaertl · 2022-12-28T07:04:41Z

#31286 could also help, with this one.

daffydock · 2022-12-28T22:32:19Z

I am currently getting this issue, I don't see a esolution to this? I am using Nextcloud Hub 3 (25.0.2)

Same here. I am only posting since this one is already closed. But perhaps should be reopened. Since like many, this one is spamming my blogs. At least for me, it spams my logs into the hundreds of MBs a week.

Edit: Worth nothing that it will usually appear when doing a cron job. But not always. I read elsewhere that someone claimed they got this error with the News app, perhaps as it was running as part of the cron, but I disabled it days ago and it seemed to slow down but alas, just got it again. It looks like it might be the notes app.

ManySolutions · 2022-12-29T07:51:19Z

I am not running the notes app. This is continuing and the error is logging around once a minute.

theonlytruth · 2023-05-31T04:53:49Z

I am running Nextcloud 26.0.2 and still getting the same error messages about every 20 seconds. I also tried to uninstall the notes app but this didn't solve the problem. Please reopen this issue or help with a solution to fix the problem.

rajeshhazari · 2023-09-21T11:42:53Z

Dear All,
I'm still seeing this error even after applying the fix manually and unable to use nextcloud from my home,
after I've upgraded from 25.0.x to 27.1.0
PHP 8.2.10
OC_Build = 2023-09-15T14:37:10+00:00

If anyone have a fix for this please share.
Thanks.
