I have problem that has occurred few weeks ago. I have one chart that I will update manually on weekly basis but now I found out that last 3 weeks it has not updated so I was studying case a bit. I had old component so I bought new one - uninstalled old component and installed latest one. All charts are shown in admin panel but when I enter new value and press render chart in admin view - all is ok. But when I click component Save or Save and close those values disappear - not saved and chart is not rendered correctly. I have old Joomla 1.5.26 and server has latest PHP 5.3.18 and MySQL 5.5.28 installed.

Any idea what has happened - I have tried in IE, FF and Chrome - all same issue. So how I can update very important chart?

Hello, there is problem with database structure. The simplest way is to uninstall component and drop all database tables with prefix jos_artiofusioncharts. Then install component again. However this process will delete all exists charts and you will have to create them again.

Hello,
that didn't solve the issue. But I found very strange solution.
I needed to do chart for 52 weeks (full year) and give value to each week. Everything went finely until week 49 appeared. Then everything got stuck - new velue was not saved. I rendered chart - looked ok - clicked save and I was thrown to main page in admin panel. Tried again - clicked save and close. Not working. Cleaned cache etc. without help.

I was using Single line 2D chart so as it shows information how I want. Changed type of chart Bar 2D and everything was shown correctly as that chart shoul. Saved now and then changed type back to Single line 2D - problem solved.

However it is not correct way to handle. Maybe you can try to reproduce issue like I did.

Hello

There is maybe plenty data to save. Charts are saved into the table jos_artiofusionchart in the column xml. There is data type text. You can use large data type as longtext. You can simply set it through PHPMyAdmin.

This didn't solve issue. See also

as it has same symptoms.

Any solution?
