I turned on the functions (PHP code) and led the command there and now the site and the administration panel writes as follows: syntactic analysis error: syntactic error, unexpected ‘src’ (t_string) in /var/www/u0389532/public_html/rdebc.ru/wp- Content/Plugins/My-Custom-Functions/Inc/Php/Functional.php (103): Eval () ‘D Code in line 1
Your My-Custom-Functions
plugin seems to be the error.
Please note Your My-Custom-Functions
plugin could not be found in the www.ads-software.com/plugins/ directory, as far as I can see.
If this was a custom plugin, you may have to go back to your developer team and ask them to make the necessary change(s) to it.
If that is a commercial plugin, we ask that you please go to their official support channel, so you can get support from the people who know it best.
Forum volunteers are also not given access to commercial products, so they would not know why it is not working properly. Other community members who may have faced your issue might be able to help you but your best bet is your product’s developer. Keep in mind we encourage you to use the official support venues, as it allows the developers to be aware of issues with their code and gives back to the community in a more robust way. Commercial products are not supported in these forums.
FYI: WP has a support forum in your language at https://ru.www.ads-software.com/support
