We have VM 1.1.9 and VM Invoice 2.0.24, and we have problems with large orders. All orders in the amount greater than 2000 cannot be edited - for example, entering 0 quantity for some items, which are currently not in stock, completely closes down VM Invoice backend and sends us to the main/starting window of Joomla backend. This weekend we had an order in the amount of 7 943.30, and we cannot edit it at all, any editing attempt kicks us out of VM Invoice backend. Is there some limit somewhere?

We're really having problems with large invoices, could someone direct me to the possible cause of this problem? Thanks.

In forum description you say "Support forum for customers who have purchased this product and have free upgrade/support period still active. Only users matching these conditions are allowed to post in this category."

Well, we have purchased your product and we have a support period still active, so can someone please answer my question? We cannot work properly if we cannot create all invoices. Thank you.

Hello,

We are sorry for late response. It is because of internal changes. Thank you for understanding.

Back to your problem:
There should be no limit. I made test order on my localhost with amount 95000 and it works fine. What about logs? Is there something what can help us understand your problem?

If not, can you send us admin and ftp access to your site to Diese E-Mail-Adresse ist gegen Spambots geschützt! Du musst JavaScript aktivieren, damit Du sie sehen kannst. ?
Please, add there also link to this topic.

Thank you for responding to my query.

We still cannot edit any large invoice, and now in addition we're occasionally getting the error when trying to preview PDF invoice for large values, it 's error memory size exhausted in components/com_vminvoice/libraries/tcpdf/tcpdf.php on line 13682. What does this mean?

Hello,

you can try to enlarge memory_limit in php settings. I would like to know how large is that pdf file.
PDF files from TCPDF also contain information about fonts. Is you use fonts with full utf8 charset, it will also make your final pdf huge. So it can have 1MB - 2MB. But I don't think, it can have much more, even if you have large values in PDF invoices.
