Installation impossible

"Table 'asblmarconi_' doesn't exist"
I compared the joomla : the table name was not complete. It's been corrected, but it doesn't fix anything.

For a donation: I'm all for making a donation, "all work deserves to be paid for".
However, I have to admit that I don't need JEM on the M207 site, it was just a desire on my part and above all an intellectual curiosity to understand why it is installed on one host and not the other (although the notion of sub-domain remains the key to the problem in my opinion).

McKillo is absolutely right, I don't know much about this area; I'm a basic electrician and here I'm looking after our association's site on a voluntary basis (without being paid).
But as I use JEM on the other site (also on a voluntary basis, for another charity) and I'm happy with it, this donation would be more a thank you for the work I've done than to help me out here.

I hope that one day I'll be able to replace Wordpress with Joomla in the site root. I'm just afraid I'll have to re-encode everything as the links will be different. I'm curious and I like finding solutions, but being retired isn't synonymous with having more time available ... the more free time you have, the more you want to get involved in new adventures.

Jojo12, thank you for taking the time to answer my questions.

PS: I only speak French, because when I was a student, we only learned the rudiments of Dutch or English in the technical schools in the south of Belgium.

@yakafm,

If a table wasn't in Joomla, it's possible that the data for that table is also missing, and this could be the cause why the JEM installation script doesn't detect it, resulting in the error.

The error message, hasn't changed? I assume the error should be different now, but if it's the same, compare the table's content with another Joomla installation to see if it has any default configuration. If that's the case, they can try copying the data.

One step more:
For example, you can set the 'Debug System' in Global Setting of Joomla (System tab) and set 'Error Reporting' to Maximum (server tab). If you detect any additional data about the error, please reopen this case.

There are many controlled errors, and the errors generated by JEM are usually reproducible (knowing some data), as long as the Joomla core or JEM procedures are not modified. If external actions are taken, it becomes very difficult to reproduce the error.

My response was an internal message, but sometimes I encounter situations with errors that were previously caused by users making changes without knowledge, and the side effects of those changes. That's why these types of issues are rare. I apologize if the statement may offend anyone; it's just a reality of any technical support.

I'm glad you're interested in understanding why things happen and in trying to complete your migration from WordPress to Joomla. In the forum, we try to help resolve cases, and develop new requested features that we find interesting. Although some are difficult to solve just with messages and without data. We are blind in front of the issue and cannot debug the code to find the cause of the error, I hope you understand.

And don't worry about the English, we're all learning .
