We're Moving to a New Support Platform – Starting June 1st!
We’re excited to let you know that starting June 1st, we’ll be transitioning to a new support system that will be available directly on our product websites – Amelia, wpDataTables, and Report Builder. In fact, the new support platform is already live for Amelia and wpDataTables, and we encourage you to reach out to us there.
You'll always be able to reach us through a widget in the bottom right corner of each website, where you can ask questions, report issues, or simply get assistance.
While we still do not offer live support, a new advanced, AI-powered assistant, trained on our documentation, use cases, and real conversations with our team, is there to help with basic to intermediate questions in no time.
We're doing our best to make this transition smooth and hassle-free. After June 1st, this current support website will redirect you to the new "Contact Us" pages on our product sites.
Thanks for your continued support and trust – we’re excited to bring you an even better support experience!
I have restored my database to a date when I could create a table by uploading an Excel file. However, I still get an error message "There was an error while trying to save the table! error There has been a critical error on this website".
I've attached a PDF with the error message and the excel file I'm trying to upload.
Please advise

THIS IS URGENT - I can not proceed with website development until I know this feature will work.
Hi Alfred,
The issue is that this source file has too many rows to be uploaded via WordPress.
This is not a direct limitation of our Plugin, it is more of a limitation of WordPress in general combined with your Hosting server PHP TimeOut limitations, etc.
There is a solution, though. Here are more details :
In regards to importing the data via a file,
Data that has more than few thousand rows can sometimes not be imported in this way directly via the plugin ( depending on the server) - this is a limitation that is coming from WordPress itself combined with server performance.
What you can do is, when you get errors, and it does not work importing directly through our plugin;
you can then import the file, in form of Excel, CSV, or spreadsheet directly in your database via your database management tool, such as PhPMyAdmin.
And then you will be able to create a simple SQL query based table from this database table, by using this query (for example):
SELECT * FROM table_1
This way, the table will use our server-side processing and you will work around the WordPress limitation of uploading all these rows directly.
Let us know if you have any additional questions.
Kind Regards,
Miloš Jovanović

I thought that table size might be an issue. So I created a mySQL table from the excel data, made sure there were no NULL fields (another ticket). Now, the filtering and searching does not work on this large table. This is a real problem.

Hi Alfred,
Could you show me the SQL Query that was used for this table - and I can advise if maybe some small modification/correction is needed to get the search to work?
If the ticket won't allow you to write the Query code directly, please create a TXT file and try sending it as attachment, or wrap it inside a zipped file and send it that way.
You can also check these points to save time if you wish.
Our logic is based on a PHP SQL parser which has full support for the SQL dialect for the following statement types
SELECT, INSERT, UPDATE, DELETE, REPLACE, RENAME, SHOW, SET, DROP, CREATE INDEX, CREATE TABLE, EXPLAIN and DESCRIBE.
Some of them are disabled for security reasons.
Filtering, sorting, and search may not work properly if you include:
-
So, first you can check for accent graves around the table name, if you have this, remove it...
Then, see if you used CONCAT to create any column.
If so, go into this column setting, and disable it from "global search" in the Filtering tab.

-
If none of that helps,
you can try preparing a MySQL view (which will return the data that you need, call it e.g. “view1” and then build a wpDataTables based on a simple query like "SELECT * FROM view1″.
If you need help with that, you can see our video, where we show an example of using View in our plugin.
-
Let me know If that helped, and i can take a look at the Query, as well.
Thank you
