Hi,
Thank you for the information. According to your screenshots, tips content integrated to the plugin is displayed for some reasons (and it should be hidden by default). As a rule, it happens because of browser cache or css styles which are used by other products (theme or plugin). Please clear the cache and try to visit one of the gallery pages in your admin panel.
If the problem still remains, please complete the following steps in order to detect the problem and find its solution:
1) Try activating a standard WordPress theme for a while (Twenty Fourteen, Twenty Fifteen) and check if the problem remains.
2) Try deactivating all of your plugins except Gallery by BestWebSoft and also check if the problem is still present. If it is not, activate the plugins one-by-one, meanwhile checking, after which plugin activation the problem appears again.
3) Provide your System status. Follow the next instruction – https://docs.google.com/document/d/1Wi2X8RdRGXk9kMszQy1xItJrpN0ncXgioH935MaBKtc/edit
4) Let us know about the results.
Sincerely,
BestWebSoft Support Team
