I re-created from scratch module Watch My Site. This administration module can monitor the status of the HTTP web server for up to 10 web sites. Version 2.0 is compatible only to Elxis 5.x. The interface is brand new, AJAX powered and can be integrated automatically to your frontend template (just 1 click). This means that it doesn't require external cron jobs anymore to be executed. The module will check automatically the status of the sites every 10 minutes and when there is a change (site UP or DOWN) will send you a notification via e-mail or SMS (SMS requires Elxis 5.5+). After installation the module will auto-appear in your Elxis administration dashboard page.

Try module Watch My Site, I think it is one of the coolest modules I have developed.

Reverted to previous files then updated again.
Working now.

Hello,
I set my site to offline and then updated the site to 5.5.
The process appeared to updated normally.
After it finished, I logged out and then tried to login but I received Login failed with error message Internal Server Error

I am currently in the process of comparing and analyzing changes to the template files to see what has changed.
I have a backup of the FS and DB.
I changed my configuration file manually to activate the site again.

If you have any suggestions, I look forward to seeing them.

I have also thought of that. Most probably we will do it in the near future.

Hi datahell,
it's not the same behaviour for other fields. If an admin forgets to enter a TITLE or a SUBTITLE, nothing is lost. The article simply refuses to save and there is a tooltip notification to signal the problem, e.g. Please enter a subtitle. Nothing is lost. This only happens if the SEO title is invalid that everything is lost. Yes, in a perfect world, every admin would always remember to validate their SEO title, but people are humans and make mistakes. I  humbly suggest that this behaviour could be changed if possible, so that it's the same as if someone forgets to enter a TITLE or SUBTITLE.
