[04-Dec-2021 16:50:20 Europe/Bratislava] PHP Warning: Illegal string offset 'title' in /hosting/www/demisport.sk/test/var/cache/prod/smarty/compile/46/d2/af/46d2af899bef3654de01b0402eed775c4c140d01_0.file.form.tpl.php on line 197
[04-Dec-2021 16:50:20 Europe/Bratislava] PHP Notice: Uninitialized string offset: 0 in /hosting/www/demisport.sk/test/var/cache/prod/smarty/compile/46/d2/af/46d2af899bef3654de01b0402eed775c4c140d01_0.file.form.tpl.php on line 197
which says there is an invalid string in 'title'.

Tento název s neplatný řetězcem je v souboru 46d2af899bef3654de01b0402eed775c4c140d01_0.file.form.tpl.php, který je umístěn v adresáři test/var/cache/prod/smarty/compile/46/d2/af.

There are also two comments. The "PHP Notice" statement is not usually important for operation, but one concerns AdminImportController.php and I would recommend solving it with problems with import.
Zápisy týkající se AdminImportController.php jsou:
[04-Dec-2021 16:50:20 Europe/Bratislava] PHP Notice: Undefined index: customer_group_price_1 in /hosting/www/demisport.sk/test/override/controllers/admin/AdminImportController.php on line 1496

and the second type of PHP Notice are associated with the above file:
[04-Dec-2021 16:50:20 Europe/Bratislava] PHP Notice: Undefined index: is_default in /hosting/www/demisport.sk/test/var/cache/prod/smarty/compile/46/d2/af/46d2af899bef3654de01b0402eed775c4c140d01_0.file.form.tpl.php on line 98 

 

What about that, please? I am new to PrestaShop

 

I enclose an import file where it builds.
The previous files are in the same format.

Thank you

Hi, I am a little bit confused. What were you doing?

[musicmaster]

Please open those files, look for those lines and copy them in your question.

People here are not clairvoyant and have different files than you.

Note that the second issue (with customer_group_price) concerns an override. So some module is causing that.

I'm having new troubles importing that are very similar to yours.  Did you ever find a solution?  Many thanks.
