503 error - Clearing cache fix this error ??

[BandiRoot]

Something weird, i get a 503 error but no error logs on the server or in IPB.

When i clear the cache in ACP Support, the Error is gone and the site is working again.

This happens frequently now. The hosting can not find any issue, same as me, no server errors and the servers is running fine.

 

Who has an idea ?

You would need to speak to your hosting company on this. Clearing cache in ACP is very likely coincidence here. Its likely the site is going down for quite a short period, so when you are doing this, its simply come backup. But a 503 message is a service unavailable, which is from your hosting.

Just tested @Marc Stridgen really clearing the cache immediately brings the website back online.

No coincidence here anymore.

 

I just moved to other hosting, can it be some file / folder permissions are wrong ?

Can you show me which files / folders need what permission ?

It may well be. The following need to be writable (fully)

applications
datastore
plugins
uploads and all subfolders

When its 503, as that comes from the server, you need to find out what exactly is causing it to show that. What exactly on the server errors or is waiting.

everything 777 or 755 ?

[Marc]

This depends on your hosting, and isnt a question we can directly answer. Usually those folder (not files) would be 777, however if using suPHP/suExec they would be 755 and will actually break using 777. 

[BandiRoot]

not using suPHP or suExec, thanks 

 

The files in the upload folder set to 644.

Generally then, the folders would be 777. This is however a generalisation of course, as we dont host your site

[BandiRoot]

According to the hosting these errors may cause the 503 error.

Can someone give me some advice ?

error_log

[Marc]

You need to upload a fresh set of files from your client area, as it looks like you are missing some

[BandiRoot]

If i upload them will i need to setup again ?

[Marc]

No, as you would not be deleting any files you have on there, only overwriting files that already exist

After uploading where can i find error logs ? In ACP never any error logs.

[Marc]

Either in System logs in the ACP, in system/logs on the file system, or if they are lower level than that, it would be your server error logs (only your hosting company can advise where they are located)

[BandiRoot]

Thanks Marc.

Is PHP8.1 advisable or leave it on 8.0 ?

 

[Marc]

If you have things running stable, I would leave it on 8.0. Doing too many things all at once, you are just asking for problems really. Give it some time of stable running, then make decisions on that

[BandiRoot]

Well i switched hosting, too bored with these error 503

Im uploading my files now, can i just copy over the new 4.7.3 version or is it better to update from within the installation ?

When uploading the new version is fine, do i need to run the upgrade after ?

[Marc]

You can upload the files manually if you wish to do so. You would indeed run the upgrader if you are on an earlier version, which you do from /admin/upgrade
