Hi Patrick

May I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.

Ciaran

Hi Ciaran

Email is sent.

Thanks a lot.

Patrick

Hi Patrick

Have you since been able to resolve this issue? I have logged in to your frontend and edited and saved a module without any issue.

Ciaran

Hi Ciaran

No, the problem has not been resolved yet. But thanks to your test I noticed, if you visit the page for the very first time editing of the modules sometimes works!

But as soon as you change the language it does not work anymore, even if you switch back to the default language (French, /fr).

or it works the first time, and after logout and login again it's not working anymore.

Can you please recheck?

You will find the login link on bottom of the page called "Private".

Thanks a lot.

Patrick

Thank you Patrick

I have been able to replicate this issue. I notice the issue is present with both the Layla template and the Protostar template which would indicate that the issue is unlikely to be template related. In fact, the error message appears to originate outside of Joomla. Have you any server-side security enabled that may cause this issue?

Ciaran

Hi Ciaran

Thanks a lot for your investigations. Strange, I was not able to reproduce the problem with the Protostar template.

However, I never worked with that webhoster before. I'll try to find out if it's a security issue.

Patrick

Here is what I have received from the webhoster support:

The 403 message is caused by too many error logs from an outdated template or module or special characters (maybe umlauts) in contents inside the module or theme.

Hello

You can try renaming the frontediting_modules.php file to frontediting_modules_backup.php. This will mean that Joomla will ignore this override and use the default Joomla view instead. Does this resolve the issue for you?

Ciaran

Hi

That did not solve the problem.

Meanwhile I did investigate further. The problem is caused by the firewall of the webhost. If there are a certain number of PHP errors thrown in a certain (short) time it will block access. I never have heard of this before. The webhost now did change something on the webserver (they did not tell what they have done) and now the problem is solved.

Thanks a lot for your help and have a nice weekend!

Patrick

Glad to hear you got it sorted. Still a mystery but at least you are back up and running

Thank you for the update.
