Service Unavailable The server is temporarily unable to service your request due to maintenance...

[Frank Oeffelke]

When a user tries to access the settings of his account, he gets the following error message:

 

Quote

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

 

 

I get the same error message when I try to change or query user data in the admin interface.
What can I do to fix the error?

The forum itself seems to work

Addition:
The error occurs apparently only with individual users! But then both at the user and in the admin area

[Jim M]

This would be a hosting related error in that your server is unable or hitting a configuration conflict to present the requested data. Please contact your hosting provider for assistance. If there are errors related to our software presenting an issue, please provide that information here.

The

answer from my hoster:

No problems are visible on the server. The server uses MariaDB and can use InnoDB without any problems.

[Randy Calvert]

It’s a system problem. I know your host is saying it’s not, but it is. 

[Frank Oeffelke]

I have delete one user and ak him to register new. Here is the result:

I get emailed that I need to confirm my mail address. I have done so. Next message: Registration completed successfully. But when I then want to log in, I get said message.

What should I tell the hoster? Where could be the problem?

[Frank Oeffelke]

The error message appears as soon as someone tries to log in. This also applies to users who have been here for a long time. After logging out, you can no longer log in!

In the support aerea I have 2 notices:

and

Mybe there is the problem?

The problem in the log is always the same:

You would describe the error you’re getting and ask them to investigate. As a hosting provider they have the tools and logs to see why this is happening. If they give you the same response, you may wish to escalate the issue.

You would want to change your table engine to InnoDB if that is what it says here (sorry, I don’t speak the language). You will want your hosting provider to do this after the investigation of the above.

The other error is likely unrelated to the service unavailable as that would trigger prior to our internal logging system. However, we have a fix coming for this in our next release. 

[Frank Oeffelke]

Just to be on the safe side:
The forum has existed since Invison forums have existed. I remember that once a database had to be enlarged after many new users had registered. That this database is too small again can not be the fault, right?

[Frank Oeffelke]

Hoster asks me to go back from PHP8.1 to PHP7.4 for test....

[Charles]

I would be wary of any host that tells you to use an unsupported, including for security updates, software package like PHP 7.4 

[Randy Calvert]

What version of IPB are you running?  Starting with 4.7.4, you MUST be running PHP8.  (7.4 won't work with 7.4 or 7.5)

 

[Frank Oeffelke]

Forum runs on 4.7.5

Maria DB is 10.5.18

[Frank Oeffelke]

Server on PHP 8.0 gives the same failure as on 8.1

Hoster can´t find errors...

[Frank Oeffelke]

Maybe the last update goes wrong? In November, all is OK with the forum...

[Frank Oeffelke]

I think this is the failure? But klicking on "fix this" will not solve the error...

The error doesn't have anything to do with the forum itself by the looks of it, but more with the server. As mentioned above by Charles, the host shouldn't tell their clients to use an older php version with known security issues. 

That being said, can you check the server error log and post here the most recent error messages logged?

[Marc Stridgen]

Haveyou just switched over to PHP 8 and upgraded? If so, I would suggest first of all disabling all 3rd party items. It may be that you have a 3rd party item there that is causing issues on your hosting, and your hosting is then throwing a service unavailable at you. 

As you are on 4.7.5, switching to PHP 7 is not only a bad recommendation from your host, but also not an option. The minimum requirement is PHP 8.

Your hosting company needs to tell you the reason that your hosting is showing service unavailable. That is not a message from the software. It's a message from your hosting environment

[Frank Oeffelke]

No, the change was made a while ago. Actually, I always install the updates when they are available. But I don't try all functions afterwards. Therefore I can't say since when the login error exists.

All 3rd party extensions have been removed. The last extension (deactivated until then) was "Auto Welcome". After I uninstalled it I only see a white page. No error message anymore, but also no user data... Slowly I am afraid to shoot down the forum completely...

This is the last mail from the support of the hoster:
Then the conversion to innodb should be done via PHPmyAdmin. Before you start your work, you should create a backup of the database, so that you can restore it to the current state in case of emergency.
Then a short tutorial on how to convert MyISAM to InnoDB.
Would that help?

Users get HTTP: error 500 during  login

[Frank Oeffelke]

For users who have logged in up to 11/24, I can access the profiles without any problems! Was there any update after 11/24 which could cause problems?

[Frank Oeffelke]

the server-log is full of the following message:

PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in /www/htdocs/w00afc19/start/forum/init.php on line 992', referer: https://www.flippertreff.de.....

That is one of the biggest issues. PHP is not allocating enough memory to the request. Ask your host to increase the memory max limit. 

[Frank Oeffelke]

He increased from 256MB to 512MB, but the log means it is not enough???
